    - 7-Zip could not unpack some RAR archives

    - 7-Zip File Manager could work incorrectly for unpacking from solid archives, if archive was open in 7-Zip File Manager. Also 7-Zip File Manager could leave some unpacked files in TEMP folder of Windows

    - So look your TEMP folder and remove folders that have "7z" prefix in name

    On my old laptop a while ago, I used another extractor for downloading items and extracting them. But today, when I went to download it onto my new laptop, I found out that it was not free anymore. I frantically searched the internet for an equal or better solution. When I found 7zip I though "Hell, might as well try." So long story short, 7zip really saved me! It works better and faster then Winrar and the others and it's free!

Really, i don't care about the GUI, all i want is a product that can do it's job fast and good. 7Zip is that kind of product, not like Winzip, wich is slow and don't even compare with the compression of 7zip, oh! But it have a nice GUI! I don't care! What is the secret of a good and fast product? Minimal GUI. Comparing Winzip with 7Zip is like comparing Edward (twilight) with Blade... Really!

    For just 7zip's it's great. Can't open arc's. The themepack bs from below does not skin it at all, it only changes the toolbar and the icon.
    Freearc is still a much better gui and can open or create 7zip's easily and it works in linux as well. 7zip does not have enough options and no matter what you do to the theme it changes nothing. And freearc actually works in more languages as well.

    It's a wonderful design and allows me to work very fast.

    It has a better compression and handles more formats.

    Sure it's free but , sometimes you really get what you pay for. 7-zip just continues to be far too buggy. It constantly corrupts files that it splits. The compression is practically on par with rar but it does it much slower.

    Winrar has been and still remains the king of compression utilities for a reason

    Those "certain parts of the internet" would do well to abandon the "pay for play" rar rubbish and adopt the FREE excellent compression 7z platform. It has all the important features of rar including the much vaunted splitting of archives and doesn't charge you a cent to create same.

    As to the comments on slowness, get off 32bit and run a real OS - 32-bit is at this point two years out of date for all practical and functional purposes (the break even point for drivers was two years ago).

    rar is a niche that has seen its day - time to move on.

    @Enlightenment: RAR is popular ... only for those who need it. For everyday compression, archive, 7Zip is plenty enough. I don't have WinRAR but can still uncompress it under Linux or Windows. RAR may have some advantages over 7Zip. But are they REALLY that indispensable to justify a proprietary (and closed) format? I prefer by far the Open Source 7Zip.

    7-ZIP does NOT allow you to create RAR files. RAR is the MOST popular file format for file distribution in some parts of the internet.

    Back in the slow-modem and small-hard-drive days, maximum compression was critical, but not very important any more, so 7-ZIP is too late to the party.

    I mainly use archivers for archiving multimedia contents, and even Winrar with the lowest compression beats 7-zip on highest compression. Taking that and the cluncky UI makes 7-zip more or less useless, and so it will remain for the rest of the time. It's a dead end project.

    I had trouble with the program when trying to extract a small program I had previously archived program using encryption ... it would freeze or go into some internal looping after prompting for the password. This was after opening the compressed file and trying to drag-and-drop the contents to my desktop and then being prompted for a password ... doesn't seem to support drag-and-drop on a password encrypted contents. Otherwise I like 7-Zip because of its simplicity and ease of use without creating a humongous program. Also, I like that I can drag-and-drop and what I am dragging drops exactly where I wanted it.

    In addition to 7z, ZIP, CAB, RAR, ARJ, LZH, CHM, GZIP, BZIP2, Z, TAR, CPIO, ISO, MSI, WIM, NSIS, RPM, DEB, XZ, and VHD formats, 7-Zip can now extract resources like icons from EXE files and graphic assets from SWF/FLA...yet the 7-Zip GUI continues to evolve at a snail's pace. In this release, we get a new checkbox in the Options dialog for "Single-click to open an item." I'm grateful for this free program, but I really have to wonder if the audience for extracting LZH files today is larger than the audience wanting a better GUI.

    The author explained on his forum that he jumped from version 4.65 to 9.xx because he wanted 9 to represent the year 2009. This is similar to the way ATI versions Catalyst, which may be OK for a video driver being commercially developed by an organization with solid hardware revenue and needing a constant stream of updates to fix software compatibility issues. But 7-Zip is essentially the work of one man who doesn't appear to be getting rich from it, and so (understandably) the releases tend to come erratically. It was 4 weeks from version 4.62 to 4.63, but 10 months to the following release. Therefore, knowing that you have version 9.06 installed doesn't really tell you how old or how fresh it is (unless it were the first week of January 2009). What 9.xx does accomplish is putting the version of 7-Zip closer to the current version of WinZip, seemingly as a marketing move. Perhaps the author is trying to shore up the prospects of monetizing 7-Zip in the near future. If so, I still think the GUI is where he could get more buck for the bang.

    People who use an Archiver utility and complaint about the ugly GUI are probably those who rarely use it. They probably open the GUI and wonder what they can do next. As they cannot find their way around the concept of file compression, then they finally judge on what they see which is the ugly interface.

    I wonder why the author still remains stubbornly silent on this simple detail. It is easy to put some eye candy, there are plenty of free nice icons on the Internet. If it is done, the popularity will probably soar unexpectedly.

    Still the best free archiver. Handles many, many formats. I like the ability to extract ISO type files. Very quick and stable. It's portable. All you have to do is go into the settings and check file types and right-click context menu items. One major problem is, it has problems with multi part RAR sets. 7-Zip declares them "broken", but WinRAR extracts them error free. That's an old, ongoing problem I wish Igor would fix.

    If one doesn't like the GUI in the 7-Zip file manager, all one has to do is use Windows Explorer for file management. You can extract archives with 7-Zip without ever using the 7-Zip GUI.

    What's new after 7-zip 4.65:
    - 7-Zip now supports LZMA2 compression method.
    - 7-Zip now supports XZ archives.
    - 7-Zip now can unpack NTFS, FAT, VHD and MBR archives.
    - 7-Zip now can unpack GZip, BZip2, LZMA, XZ and TAR archives from stdin.
    - 7-Zip now can open/copy/compress disk images (like \\.\c:) from \\.\ folder.
    - 7-Zip File Manager now doesn't use temp files to open nested archives
    stored without compression.
    - New -scrc switch to calculate total CRC-32 during extracting / testing.
    - Some bugs were fixed.

    Don't use this alpha version for important data. Call "Test" command after each compressing operation.

    Jafo818, this is because 7-zip hooks into your explorer shell so it can give content menu options when rightclicking on files. Your shell locks its hook file so it needs to reboot in order to delete or update a file after installation unless you aren't running explorer.

    Anyway, this is the best file archiver out there. As everyone else says, the GUI leaves a little to be desired (and they still haven't fixed the long-standing bug where if you try to extract files to a directory that doesn't exist, it errors out (instead of asking if you want the target directory to be created)), but whatever.

    An excellent archiver however there are two issues I'd like to mention about: at first, Igor is reluctant to add multimedia filters, thus 7zip lags behind WinRAR when compressing bitmap images and raw sound files (such as CDDA audio in WAV format); at second 32bit version of 7-zip doesn't allow using a 128MB dictionary (this is an artificial limitation imposed by Igor - 32bit Windows can handle such dictionary size just fine).

    Reviewing 4.63 (Jan 1, 2009)

    anonymouscowturd, you can update 7z archives just fine, as long as they are not Solid. The problem is that Solid is automatically set by default in the GUI if you choose anything in the Compression level drop-down list other than Store. You can override it by choosing Non-solid in the Solid Block size drop-down list, but you cannot customize the Compression level choices to remember this. This is just one of many long-standing annoyances about the GUI. People look at the GUI and say it's not so bad, but that's solely based on superficial appearance. As we can see from anonymouscowturd's confusion, the awkward design of the GUI is leading people to think that certain capabilities aren't available. Go to the command-line, you might say. Well if you (or someone else) already created a Solid 7z archive due to the clumsy GUI, you'll simply get a terse error from the command-line when trying to update it, not a clear explanation of what's going on and why. Frankly, I think WinRAR's GUI is ugly and does a poor job presenting its Compression Profiles feature and shell Integration options in the Settings dialog. BUT it has never misled me about what I can do with RAR archives, and it's always obvious how to do it.

    Eh? Resiliency not needed? If the CRC check fails, that's exactly when you need resiliency. And RAR's recovery record helps with that. It's not perfect (especially with a default 3% recovery record size), but at least it's a chance, whereas the 7-Zip format gives you nothing.

    7-Zip doesn't "handle RAR". It can unpack them but not create them. So, this is about formats. All I ever hear is how great 7-Zip is, as a format. Well, my opinion is that it's not all it's cracked up to be.

    As far as WinRAR being shareware goes, it's not expensive, and it has a lifetime license. Give me a break.

    It can be configured for context menu functionality, just like WinRAR, and works great with FreeCommander and PowerDesk Pro 5 in that capacity.

    It also has a pretty slick File Manager interface that you can setup as a dual-pane Norton Commander / Total Commander / Free Commander type of app.

    In *my* tests 7zip seems to always come out in front (make sure you use maximum compression settings). For those whining about the GUI, go get Jzip (www.jzip.com) which is a free WinZIP-like interface built on 7zip technology, and also works with regular ZIP and RAR. It also has "webmail integration" that automatically compresses files when you attach them to your web-based email. No, I don't work for the company. Just a bit of info for the whiners.

    If you're really interested in better compression, neither 7Zip or WinRAR can touch some of the other archivers coming mainly out of Eastern Europe. See discussions http://encode.ru/forum and try products like WinUDA - slow as molasses and not SMP-enabled, but will always make tinier archives than either of the popular formats. Also check out http://freearc.org and http://sourceforge.net/projects/peazip/.

    Wonderful software. It offers pretty much everything WinRAR does at the moment, except .RAR archiving because of copyright restrictions. Never had a problem with extracting .RAR archives so far. Deleting, modifying and updating files within an achive (.zip and .7zip) work very well in the latest 4.58 Beta.

    This is a brilliant free program... But, it desperately needs the ability to overwrite only older files on extraction to make it worth having over other free choices.
    Also the interface could do with a lick of paint...

    - Some speed optimizations.
    - 7-Zip now can unpack .lzma archives.
    - Unicode (UTF-8) support for filenames in .ZIP archives. Now there are 3 modes:
    1) Default mode: 7-Zip uses UTF-8, if the local code page doesn't contain required symbols.
    2) -mcu switch: 7-Zip uses UTF-8, if there are non-ASCII symbols.
    3) -mcl switch: 7-Zip uses local code page.
    - Now it's possible to store file creation time in 7z and ZIP archives (-mtc switch).
    - 7-Zip now can unpack multivolume RAR archives created with
    "old style volume names" scheme and names *.001, *.002, ...
    - Now it's possible to use -mSW- and -mSW+ switches instead of -mSW=off and -mSW=on
    - Some bugs were fixed.
    - New localizations: Punjabi (Indian), Pashto.

    What do you need a GUI for?
    Select the folders and/or files you want to compress, right click, "add to archive" and there you go. Same works for unpacking archives.

    Don't even bother with ACE. It has horribly buggy/insecure code which can be and is actively exploited by malware authors. These days the malware authors exploit any common file format. DOC, XLS, PPT, PDF, ZIP, RAR, Flash, QuickTime, RM, MP3, WMV... :(

    As for competing with RAR, I too guess that RAR would do alot better if they finally would allow larger dictionaries than 4 MB. Why they don't upgrade that?!?!? Anyway, 7z is free and open source and has better compression than RAR usually.

    If and if only if WinRAR will allow creation of more than 4MB Dictionary size, it will crush 7Zip.

    5 stars all the way, and a devoted 64bit version aswell, which is a lot faster on my win xp 64bit machine,

    still no support for ACE archives though, strange why ACE company has to be so restrictive when it comes to there format,

    i'm starting to think it's this kind of bahaviour that's caused there format to come to an end,

    ACE had a lot of potential, on many types of data, it was faster and better compression then RAR, but of course nothing comes close to 7zips format,
    LZMA.

    http://en.wikipedia.org/wiki/7-Zip

    one problem should be noted though, for some reason 7Zip sometimes detects the wrong amount of cores available, and on my system chooses 4 cores for multithreading when in fact i only have 2, a small bug, doesn't warrant loosing any points,

    Do you mean explorer integration via an archive-as-folder kind of function? I don't see how this would save you any steps. As it is now you double-click an associated archive, it opens, you drag-and-drop. That the window title is 7-Zip rather than Windows Explorer is neither here nor there. For multiple archive operations 7-Zip's 2 panel view could arguably be more efficient.

    bigspud: it's not a bug. Yes to All only applies to all files in the current archive. It is reset when 7-zip extracts a new archive, which makes sense because you may have a lot of files from one archive to overwrite but you might not want files overwritten from an unrelated archive. Perhaps there should be a "Yes to All Archives" option but then you might risk providing too many options on a form.

    7zip is almost always my choice for compressing and opening archives. I wish it could deal with sfx files. :-)
    The Gui's fine, IMO. Look in the menus for minor surprise features. eg, you'll see you can choose flat view (like winzip) or tree view (like win explorer). you can have two-panes view (i haven't yet found use for this in a compression app, but it might be good for editing a file, then dragging result back into the archive).

    The Good: *Small, light, fast. *Light, clean GUI. *Portable, sort of. Free, updated regularly.

    The bad: *Reports some multi-part RAR archives as "broken", when WinRAR can extract them just fine. *The program is "memory locked", for want of a better word. That means you can not delete an open archive, or edit a file inside an open archive. Don't know why, it should be easy to fix. *Needs a "Register File Types and Create Context Menus" button. *Needs to release itself from memory. Once used, the program files can not be deleted or moved until a fresh Windows boot.

    That may sound like a lot of bad, but it's still fine program. It's greatly appreciated, believe me.

    7zip has issues opening RAR files with the .001 .002 .003 and so on numbering sequence when no .rar file exists. It will treat each file in the sequence as a individual archive instead of following the sequence and extracting all of them. It results in a broken incomplete file. This is the only negative issue with 7zip I have and it is otherwise an excellent program.

    I'll rate it a 4 because 7za.exe remains very good, stable (I didn't have major problems even with beta releases), and has an excellent compression rate, even when using the ZIP format (since I myself tend to always use ZIP for better compatibility).

Rating it low b/c of a few icons is going overboard. Personally, I don't find that WinRAR has better interface. But definitely, Igor should think of improving the GUI of 7Zip to attract more users as this seems to be the criteria some people judge a product.

    It's light, it's intuitive and it's functional.

    The GUI does have a couple of quirks, for instance: the toolbars have an unneeded useless function of moving the right part of the toolbar to the right, and the menu isn't skinned by the Windows theming service. Other than that, the GUI is more or less perfect: simple, intuitive, functional and neat.

    What I do wish is that the command line switches be given documentation. I have searched, but it appears that there is none.

    To judge an application on interface alone shows lack of experience with computers. I agree that I am not particularly fond of the gui but I have installed this on countless noob's PCs and they have had no problems opening RAR/CAB/ZIP etc. It is tiny and fast, no nags, ads or crippled functions.
    The functionality alone makes up for the simplistic gui which as I stated is not difficult to figure out.

    I use WinRAR myself and but it's not free and more for power users that are constantly archiving and uploading files.

    Oh yeah, is winrar free? No.
    Is it open source? No.
    Can it be installed via command line in less than a second? No.
    Get with the times. winrar is fast, it does have a more polished gui, but for people that want a great zip/unzip program, free, open source, this is the only choice.

    Good but not the best, Winrar rules the roost there. But best of the opensource lot. Good compression ration but only really as good as winrar, the interface needs some work as does the speed of the algorithm which is quite frankly terrible when compared to winzip or winrar, its closest competitors.

    Great program. It really is portable. You can install, then zip up the install folders and transfer it to your USB flash drive. Launch it, set the file associations and shell options, and voila! It has a feature lacking in all the rest: A context menu item "Open Archive with 7-Zip". You would be surprised how many install programs are SFX's, and it's easy to find them with 7-Zip.

    .5 points off for lack of internal editing, .5 points off for getting errors on many large multi-part RAR archive sets. The author knows about these issues.

    Small size and very fast. Freeware with no nags or bloat. Interface is not the prettiest but I have installed this on several PCs and users can open compressed files they receive easily.

    I have read the comments and have just downloaded IZARC and will be checking it out especially since they have a portable version that runs off a USB flash drive.

    Someone mentioned the fact that 7-zip does not support ARC or ACE. 55% of what is downloaded from P2P/Usenet is in RAR format, 20% in ZIP (only because Windows has ZIP support built-in) and the remainder in TAR/GZ with a maybe 5% in 7Z format which is truthfully the only reason I have 7Zip on my system as I already have WinRAR.

    I used to have WinACE when I was running Windows 98 and even then most things required ZIP/RAR and occasionally ARJ. It's been literally YEARS since I have run across anything compressed with ACE or even ARC (MS-DOS and BBS era). It is probably good to have software that supports obsolete compression schemes for software stored on floppy diskettes and ZIP drives but you can definitely live without it.

    Neither 7zip NOR izarc can compare themselves to winrar because neither of those two can compress multiple files to multiple archives as can winrar.

    I like the program a lot, but it needs to catch up. It throws a lot of errors extracting multi part RAR archives, which WinRAR then extracts flawlessly. 7-Zip does not release an open archive file from memory like WinRAR, meaning you can not delete an open archive or edit an internal file. Fix those 2 issues, and you have a top notch archiver that I prefer to WinRAR.

    I agree that the interface is not perfect (but you don't have to use it, and it doesn't increase the code size dramatically), and some additional options like WinRAR's error recovery information would be nice.

    However, 7-zip is a fast compression solution, the integration of different formats is splendid, I haven't encountered any bugs, and for a freeware solution this is much more than I could reasonably expect.

    I really think this is one of the better free / open source efforts out there in terms of utilities, and I'm grateful to the contributors for keeping this thing going. Well done indeed.

    I do also have troubles with multi-segmented RAR archives, as is mentioned in these comments by others, but thankfully, I do have a WinRAR license to deal with those. But overall, 7zip is so good that I do like to use it to compliment WinRAR. It's great to have options, especially free ones.

    As soon as I can rightclick a set of files & create an archive for each individual file I will use this. If one has a group of files & you want each in there own archive you must do one at a time (LAME). If I had a business & distributed files I would buy winrar period. There seems to be tons of info in the help file about compression/decompression but naught else.
    As far as 'treating' zips as folders that can be done in xp for free in several ways, compression included.
    BTW winrar had better compression than this lame 'zip' mgr from my test. (I use fastest) default compression settings both. At least you don't have to reboot anymore for it to install. That is the only update I can see worth mentioning.

    Actually, WinRAR *does* have this feature. Only, its intelligent. It shows it only when it detects that the exe is an archive. Try creating a RAR-SFX and right-clicking. Or even more advanced, try embedding a RAR in a JPEG or something. WinRAR will be able to detect the RAR and show the "Open with winrar" option.

    7-Zip alpha 1 is already available from http://www.7-zip.org/alpha/7z445a1.exe

    What's new:
    - Now it's possible to specify the size of solid block and the number of CPU threads in "Add to archive" dialog box.
    - Default dictionary size was increased: Normal: 16 MB, Max: 32 MB.
    - Speed optimizations.
    - Benchmark was improved (new "b" command in command line version).
    - Some bugs were fixed.
    - New localization: Welsh.
    - Some error messages were changed.
    - Undocumented feature "\\.\a:\" now allows to write disk images to floppy.

    I personally think that this release is great. I like the support of multithread processors. My CPU is only dual-core but my friend has a quad core processor, and this release utilises all 4 cores in almost 100%. Believe me, that such kind of apps are quite rare (most of them use only two cores in nearly 100%, and the other two are just lazing...). Moreover, it can create multivolume archives - something what quite a lot users asked for.

    I have used 7-Zip since v.3.xx. 3.xx (AFAIR 3.12) was horrible - lacked uninstall option, the compression ratio was worse than WinRAR and it compressed archives much (around 300%!!) longer than WinRAR (I am comparing it to WinRAR because it is the only serious competitor. There are some exotic ones, but their popularity is limited. Zip is popular but obsolete). When you compare it to WinRAR (which have been developed too!) today, you will see that the compession ratio is in 90% of all cases better and the time of compression is only 40% longer compared to WinRAR 3.61. What is important 7-Zip loves new processor architectures and new OSes, what you can see if you compare WinRAR and 7-Zip running e.g. in multicore environments or Win XP 64-bit. Believe or not, but 7-Zip 64-bit is faster than WinRAR if you use dual & quad core processors. I know that the comparison is a bit unfair, because there is no 64-bit WinRAR but it shows the progress in the development of 7-Zip.

    An ok compression tool. >May< squeeze a few more bits out while it compresses. But it does so at a BIG cost of time and CPU.

    I have over 500 Gb of disk space, I'm not crying over a small size difference.

    I'll stick with WinRAR, incomparable tool. Ease of use, formats supported, and best for me, when I unarchive something I get the exact directory structure I started with.

    With 7z and zip I drag and drop, choose to unpack, I get the archive name as a folder and another folder under that. Annoying.

    If you are a starving artist, I guess free is attractive. When you get a few shillings, spring for WinRAR.

    7-Zip is far superior to both winzip and winrar. The compression ratio is higher, its simple, its fast, its convinient. The only thing that would help it out would be if it would associate .zip and .rar and .7z file with itself on installation or something. I can do it manually, but the average user could not.

    Those who ask for a eye candy skin are probably the lazy slaves of the Zip format. They are too scared of trying another compression format. 7Zip's simple GUI is a convenient pretext for them to justify the lack of openess of their mind.

    Nevertheless, if the author implements some nice icons that would definitely help to increase the popularity that 7Zip desserves. I guess he just needs to express the request and there will plenty of art designers who will jump in to give him a helpful hand.

    Good to see this continually updated. :)

    I too use the right-click menu and don't use the interface that much, however, WinRAR has allowed skinning and it hasn't seemed to slow that app down one single bit. You don't have to use the skins if you don't want to. You can leave it with the default skin if you wish.

    No harm, no foul. :)

    JOCO - I don't understand your comment at all. How do you get to thinking that just because folks might like some new icons, they are as you describe? It makes no sense at all, at least at first glance.

    I use WinRAR and 7zip but also like eye candy, for example. I seldom ever bother calling up the main GUI in either program, but appreciate an attractive interface when I do call 'em up. I have a feeling that many others are the same way.

    A bit quirky (no error messages when you open archives 7-zip doesn't understand), but overall it handles a number of archive formats, especially ZIP and RAR, and it can make both, and it has a right-click shell extension. AND it's free. Thus I use it.

    Only thing it lacks is to allow you to add right-click options specific to any format 7-zip supports (not just 7z) such as "Compress to ZIP" so I don't have to go through a dialog, even just to hit OK.

    WinRAR has a more advanced interface and excels in data recovery features, but 7-Zip is clearly the best FREE standard zip program; the format specification is very versatile, and it is open source. Also, the 7z-format may be a little tighter than RAR in many cases.

    I agree, and I've been saying it for years. PowerArchiver has done the most with the 7z format.

    There's a lot to like about 7-Zip. It's fast. It has a light, uncluttered GUI. It has great shell extensions. It handles multiples well. It's in constant development, always a good thing. It works great on a portable USB drive.

    There is also a fairly long list of deficinecies. It does not handle most commen ISO-type image files. It keeps the active archive in memory, not allowing you to delete the zip file after extraction (until you close the program). It does not allow editing and saving within an archive, which is akin to the same memory problem as above. It can not handle the occasional multi-part RAR archives (reports damaged files), forcing me to download and temporarily install WinRAR. Drag-and-drop is not supported.

    7-Zip may be the best general purpose free to use archiver. Certainly it's native 7z compression format is either the best or among the best at creating the smallest archives. You can also set it's default archiving format to zip if you like.

    7-zip is a little quirky to use in my opinion, with some minor annoying bugs. That being said, if I could not afford shareware, 7-zip might be the archiver I would choose.

    Works pretty good, and the price is right. As another reviewer mentioned, you still need Winzip for those files that were compressed with Winzip's newer tighter compression. Same for WinRAR, WinRAR can't open the high compresion Winzip format. I have ran into several of these files recently.

    Here is the Changelog (from 7-Zip forum):

    What's new:
    - 7-Zip now can use multi-threading mode for compressing to .zip archives.
    - 7-Zip now uses order list (list of extensions) for files sorting for compressing
    to .7z archives. It can slightly increase compression ratio in some cases.
    - 7-Zip now can unpack some incorrect .zip archives (archives with incorrect headers).

And yes, you need to keep the ol Winzip at hand for the case that you get a zip-file that was non-standard, proprietary compressed! 'Kaizen' I'd say....its getting better all the time :>)

Corel makes some localised versions of WordPerfect (e.g. Spanish and French) but the shortcuts are tied to the language of Corel WordPerfect only. If you work in multinational environments WordPerfect is a nightmare. I wrote a letter to Corel two or three years ago but their answer was something like "yes, we know about it". Nothing about the solution of the problem. Pity.

    zridling, adding ALT+A and ALT+E shortcuts is not so easy as you think. From my own experience: the shortcuts may collide with global shortcuts in Central European Windows (eg Alt+A = ą, Alt+E = ę). Of course, one can remap his keyboard, but I just want to let you know that it is not so simple as it looks. Many companies overlook the problem, eg. latest ATI drivers (with CCC) are barely usable for Czech, Slovak and Polish Windows (and maybe some more) users. Corel WordPerfect is unusable for a half of Europe, just because of its shortcuts.

    I wouldn't mind if the GUI were simply clunky. What I do mind is that longstanding, obvious bugs in the GUI never get fixed. For example, the Test button on the toolbar simply doesn't work. If you enable the Explorer shell extension and use Test from the context menu, it works fine. How hard would it really be to connect the toolbar button to the function which the context menu performs? There are lots of similar examples in 7-Zip, and while they don't bother ME much, they make it very difficult for me to recommend 7-Zip to average users who are typically accustomed to the polished GUI of WinZip. Therefore, the 7z format is handy for me to archive my own stuff for myself, but lousy for exchanging files with others. Sure, I could have self-extractors but then you run into security issues from sending exe files around. For 7z to stand a chance at becoming the successor to zip, 7-Zip needs to get around to fixing the obvious bugs.

    The earlier poster who claimed Squeez is able to create RAR files thanks to licensing, you are mistaken. SpeedProject reverse-engineered the 2.0 version of the RAR format and implemented it themselves; Rarsoft does not license code for RAR creation to anyone. In fact, SpeedProject says so themselves: "The developers of those formats make sure that only their own programs can compress RAR and ACE archives, there is no support for the developers of other archivers." (from speedproject.de/enu/squeez/tour2b.html)

    Although SpeedProject's reverse-engineering is impressive, current versions of WinRAR create new RAR files using version 2.9 of the RAR format which makes them smaller and able to support more features.

    This version of 7-Zip also introduces some impressive reverse-engineering. The Nullsoft forums are buzzing with horror over 7-Zip's ability to extract most NSI installers. People have come up with techniques to block 7-Zip extraction, so it will be interesting to see if this turns into a DRM-like war.

    I like it, but have two concerns.

    First, no way to provide 'repair' info that I can see. RAR files can add a recovery record as large as you like. I usually add 3%.

    Second, I can't find a way to create a 7z file that will unpack to the proper directory. Example:

    C:\SomeFiles\

    Use 7-Zip to compress the files in that directory.

    Unpack the 7z file to C:

    I always get C:\SomeFiles\SomeFiles\

    Again, RAR does not do this. Maybe I'm missing some obvious switch, but it is not evident to me.

    Still can't figure out how people can just gush on about the compression when the difference in comparison to Winrar are pretty much next to nothing. Still takes longer to actually compress files then WinRar and IMO is progressing just as slow. Still a good format don't get me wrong but I just dont like it as much as Winrar

    I've been using 7-Zip since early betas and it has matured since then and have become a program I like quite a lot, and use along with WinRAR. Ever tried sending something to a person that is both on modem and knows nothing about computers? 7-zip the whole thing into an executable self extractor and fire away. Really need to compress something before you make a backup? There you go. It is for these moments 7-zip shines, at least for me.

    Kramy, the 7-zip compression is superior to the WinRAR compression, however WinRAR can decompress 7-zip archives just fine, and WinRAR interface and intergration into windows is far superior compared to 7-zip. In the end it comes to user preferences but I wouldnt recommend 7-zip over WinRAR to anyone just because it can squeeze down some files another little bit. Many advanced users probably prefer 7-zip over WinRAR because of its better compression and better command-line tools, but other advanced users like myself dont have much need for that either.

    I'm using 7-zip in one project for batch-compressing multiple directories into a .jar for firefox extension packaging, couldnt get WinRAR to do that from command line, but for general compression and decompression i use WinRAR. But 7-zip is excellent software and it is fully free, WinRAR is "just" quality shareware.

    Kramy, I take it you've never really used WinRAR? RAR is the standard for file sharing because of its reliability. But that takes nothing away from 7z. Other apps compress using either RAR or 7z, so it's a matter of personal preference whether one uses 7-Zip, WinRAR, PowerArchiver, or Squeeze for that matter. But never underestimate the value of a good interface; it's essential to building good software period.

    zridling: I haven't used WinRAR 3.5x, but I've used older versions in the past, and they were in every way inferior to 7-Zip. WinRAR 3.5 caught it up in most aspects, so it comes down to personal preference.

    If you're wondering how I can compare them while not using the latest version, it's because I recompress every zip archive I download. Even multi-gigabyte archives, and so far 100% of stuff has come out smaller.

    Perhaps that just means RAR users are stupid, but I prefer to assume it's a program flaw and not just the congregation of morons. Perhaps I am wrong?

    ============================================

    If you use 7-zip's LZMA compressing with proper settings and make it a solid archive, it will always beat a RAR. :)

    It also zips faster, but WinRAR and 7-Zip appeal to different groups. 7-Zip appeals to the power user that uses right-click menus, batch scripts, and ocassionally looks inside an Archive. WinRAR seems to appeal to home users that value a pretty interface. But then, if I valued a pretty interface, I wouldn't be on windows. :P

    I'm tired of seeing kids confuse the 7-Zip program and the 7-Zip compression algo. The program is pretty bare-bones, with a lackluster interface that leaves me turning back to WinRAR.

    As for the algo, well prove to me that it's better than RAR. Yes, it's free and open, and that counts for a LOT, but technically, it's not so cut and dry. 7-Zip compression works better than RAR sometimes, not as well other times, and can be glacially slow and demanding of memory.

    No one is arguing compression algorithms — the 7z format is not the same as 7-Zip the program. Overall, WinRAR's many features and long, reliable track record make it first choice head and shoulders above any other archive tool — just cruise usenet on any given day or decade. What's not to love about 7z? It's 7-Zip I want to see improve in measurable ways that users have wanted for years.

    I agree with you completely Zridling. I am not a "monkey see.... monkey do" type of person. Just because the majority of the PC populas uses some favor of ZIP does not mean I do.

    Great archiver, but I really really wish the author address the "stuck in memory" issue. A component loads with Windows start, and it prevents installing without a re-boot. Another thing that is very unusual is that an open archive can not be deleted. WinZip, WinRAR, and IZArc do not exhibit this problem. You can delete an open archive, then close the GUI.

Does not release archive from memory, therefore not allowing you to delete the archive until you exit the program. (WinRAR, IZArc Etc. do allow this)

    Reviewing 4.33 Alpha 1 (Jan 25, 2006)

    In addition to the usual minor bug fixes, this version changes some algorithms and default settings which affect dictionary size, memory requirements, and speed. In general, compression is faster but not as tight (meaning files are slightly larger; author is working on tuning this aspect further). Compression is tighter for Ultra mode of the zip format, but I rarely use 7-Zip to compress in zip format and never in Ultra mode.

    I don't hate the appearance of the UI, but I do hate the bugs. The file sizes displayed are randomly right/wrong. Numerous toolbar and menu functions simply don't work from inside the UI but the program obviously implements those functions because they work from the context menu. Shell integration clobbers your ability to select and open multiple files of certain types from Explorer; you wind up with 7-Zip opening instead (even when none of the files were 7z nor any other kind of archive associated with 7-Zip).

    These are bugs which have gone unfixed for many, many releases, and even the most pathetic WinZip clones are able to get these things right. I don't think it's unreasonable to rate 7-zip a 4 until it makes some progress.

    Good archive program. Great stability and speed. Easy to update because it remembers your custom install folder. Yes, the UI is a little plain, but large garish icons can bloat up a program and drag down performance. Serious archive users seldom use the UI anyway. They use the Explorer shell context menu, which is fine in 7z. Windows already has an Explorer, so an Explorer view in an archive program is arguably redundant.

    Here are the only important shortcomings I have found in 7z:

    *Needs various ISO file type (ISO, IMG, BIN, NRG, MDS, Etc) support, (like IZArc).

    *Needs to release open archives so they can be deleted before closing. (like WinRAR, IZArc).

    *Needs a "Checkout" option (Like IZArc, WinZip)

    *Needs to give an error message when attempting to open a bad archive instead of showing the Explorer view. (What's up with that, anyway?)

    In addition, I would REALLY like to see a portable (no install) version of 7z. The DLL's and file types could be registered with 1 click in the "Options" menu. It would be dynamite on a USB flash drive!

    I score 7z a 4.6 out of 5. I think 7z is tied with IZArc. IZArc is a more complete program, but it's cumbersome install and general performance are not as good as 7z.

    The software is very good, goes well, and gives the competition a run for its money - especially as this one's free.
    The GUI is a blast form the past tho. Looks like the icons were made in Paintbrush. Get in touch with me and I'll design the GUI for free if you like.

    Version 4.30 shows major increase in speed for ULTRA (up to 30%), that keep latest 7z wins over latest WinRAR in compress / decompress speeds and compress ratio.
    I suggest You test 7-zip's ultra, normal and fast against WinRAR's best, main goal is resulting size but often 7-zip's normal/fast wins over WinRAR's best while still being FASTER!
    7-zip hold the crown, followed by WiNRAR. I fail to see how nifty GUI results into better compression ... most of users uses cmdline and context menu like more often and in that they equal...
    programs like Squeeze contains 7z format support because they can GO and take the source and implement it ... lol ... while You can't go and put compressing support of .sqz or .rar into Your program "free of cost"
    You can see the trend when more and more sw and game developers using 7z and/or bzip2 instead something like .rar or .sqz. Reason? Source code/SDK , features, usage, speed, cost, quality etc.

    Well its out of alpha stage and lookin' good.

    It should be considerably faster on win64 considering it supports the new memory page size.
    Its also smaller since all those extra executables were removed.

    I'm not sure whether to call this professional quality, but it does what it does veerrry well.

    And dont just bash this due to the interface, its about quality. And the 7z archive format proves that.

    I can tolerate the homely GUI and 16 color icons without too much pain. However, I'm lost without a "checkout" feature and ISO support.

    Other annoyances: "Yes to all" button does not work on multiple file unzip. Open archives are "locked", and you can not delete the archive until it's closed. That indicates poor memory and CPU management.

    On the positive side, it's small, light, quick, and stable. The install program remembers your custom install folder. This makes installing each new alpha a snap. BTW, this release is only for Win98 and ME users. The author really should be nice and post a change log.

    People complain of primitive interfaces, but can you select word length and dictionary size in WinRar?

    These things let you truly customize how it compresses on your system. In the past 7z compression was nearly twice as good as Rar, and much quicker!

    Now Rar is starting to catch up, but if you actually know what you're doing you can still beat Rar's compression ratios in less time. Ever since 7-zip shrunk a Rar'd ISO to 40% the Rar size(a month ago) I've believed it has the best compression.(2.6gb -> 1.16gb)

    I completely agree with httpd.confused, 7z format is excellent, but 7-Zip the application has a primative interface, this in turn denies it top place as my achiever.

    In terms of interface (which i regard as THE most easiest to code & important aspect of ANY program), WinRaR beats 7-zip to a bloody pulp.

    And a excellent interface *is* important for any program, because what is the point of having good coding, without the streamless ability to execute it's featured abilities with ease and maximum utilisation?

    That's like having the engine of a formular one racing car in a public bus, it just doesn't make any sence.

    Now that being said, the one thing i did like about 7-Zip (apart from it being free) is the speed information which is provided that WinRaR doesn't seem to have the option for.

    When the interface of 7-Zip *greatly* improves, i'll probably switch over, but till then.

    Slooooooooooooooooooooooooooooooooooow and compression is on par or only slightly better than Winrar. The difference in compression between Winrar and 7-zip is not enough to warrant the speed difference. Still buggy(yes I know its an alpha release) Maybe one day it will be the best but that day aint here yet and till then the best is still Winrar
    Top 3
    1)Winrar = Best combination of speed and compression(highest compression along with 7-zip in my tests)
    2)PowerArchiver = Good options, speed and look

    Someone asked below: "And I love the typical "I'd like to see you do better" comment. Does it make sense to say that?" (et cons.). My answer is: of course! I cannot make a film or a car by myself (at least with so called professional movies and cars which are not made by small companies like Sbarro, Jaehle, ABT etc. which tune up something which is made by other companies rather than build cars from scratch).

    Igor Pavlov proves that it is possible with archivers. He makes 7-Zip by himself only. So if you know how to make a better archiver do not lose your precious time - just prove your skills by making something better, which would be relatively easy because 7-Zip is an open source application, so you can use some portions of the source code. Everybody waits for archivers which compress twice faster than 7-Zip, compress better than 7-Zip, and their interfaces are more beautiful than 7-Zip (however, I remember that "beauty is in the eye of the beholder")

    PS And my personal advice: it is nice to be important but it is even more important to be nice.

    UPDATE. Some asked about the difference between Z-zip 4.29 and the newest one. Well, the new one compresses MUCH faster! The test below is not made by me, but I observed similar results, so I can paste it here.

    Machine: Intel Pentium M 1.7 GHz, 400 MHz FSB, 512 MB DDR-RAM, Windows XP SP2 Software: 7-Zip 4.29 Beta vs. 7-Zip 4.30 Alpha 9 Parameters: LZMA, Ultra, 32 MB Dictionary, Solid compression

    I have used two program directories for testing. So there are many different file types included in these packages (binaries, text documents, images etc.).

    Adobe Acrobat Reader 5.0 Program Directory
    Uncompressed: 15,769,412 Bytes 7z429: 5,212,596 Bytes [33.06%] (time: 25 s) 7z430: 5,209,338 Bytes [33.03%] (time: 18 s)

    Uncompressed: 216,283,797 Bytes 7z429: 60,683,275 Bytes [28.06%] (time: 7 min 26 s) 7z430: 60,630,702 Bytes [28.03%] (time: 5 min 36 s)

    Hope this gives an impression how 7-Zip performs in general. Although there is only a very small improvement in compression I highly witness the improvement in compression speed! Amazing work, Igor!!!

    I still hate the utterly rudimentary interface. And I care next to nothing about its open source status. The 7z format, yes, but the 7-Zip application, no.

    Please feel free to show your immaturity by personally attacking me, for my having dared to give an honest review of this bit of freeware.

    As always, I have been addressed. You kids can't seem to avoid it, huh? Anyway, ModderXManiac, it does make sense to rate based on the interface. You see, it is an application, and modern applications have these things we call interfaces. Some are good, some are bad, some are in between.

    The 7z format is not the same thing as the 7-Zip application. I was rating the latter, not the former. Try to understand this.

    There are plenty of archivers that work with the 7z format. Many of them have better interfaces than 7-Zip.

    And I love the typical "I'd like to see you do better" comment. Does it make sense to say that? Let's see... Have you ever commented negatively on a movie you saw? Of course you have. But how dare you! Could you make a better movie? What about a car--ever complained about one, or criticized the way one looked or worked? Of course. Can you build a better car yourself? By now, everyone but the people who repeated first grade a dozen times get it. Now get over yourself.

    You see, this is how it works: You get your review, and I get mine. You can place value where you want to, and I'll do likewise.

    Why does some fool always think I want skins when I complain about an interface? If you don't care about ease-of-use, and just want free, good for you. I'll use the same 7z format you are, but with a better interface.

    By the way, I used to be a software engineer, so yeah, FYI, I could make a better interface.

    I love the high compression ratios using the 7z format, but as for the official 7z archiving app, the gui is pretty average. I prefer Tugzip, which is also freeware, and achieves the same 7z ratios, as well as support for creating rar, ace, and sqx. sqx has nearly as good compression as 7z, but allows you to ecrypt the file names as well, so nobody can even see what kind of files are in your archive.

    Bobad, those things are so minor. I actually lower a rating when I see some of those those, since it's annoying having every program under the sun asking you if you'll let it handle stuff.

    ISO support is on the list of thinks to add in the future. When it is, I'm dropping Nero in favour of 7-Zip + DVD Decrypter.

    I like 7-Zip's simple and advanced interface that lets you customize how it zips. I've been using it several years now, and I seem to be getting better and better at predicting the compression time based on files types and compression method.

    Also, no other zipper that I know of comes close to 7-Zip's Solid Archive mode. Although the entire archive must be extracted to access the contents, it allows VASTLY better compression. An example would be the Java 1.4.2 docs that are 177mb(195mb on disk), 32.80mb zipped, and 9.62mb 7-zipped at 64mb dictionary.

    Simply awesome!

    Being used to IZArc, I miss the "checkout" function and the support for ISO archives. Such a shame. I also wish for portability, enabling 7-Zip to run on a USB flash drive. On first launch, the program could check for archive associations and offer to register the file types, and become the default archiver.

    Hey, I'm the first to cheerlead the 7z format, and I do in fact use 7-Zip on a daily basis. I love 7z and hope it supplants ZIP asap in every app. But it seems many here equate 7z the format with 7-Zip the program. I'm evaluating 7-Zip, not 7z. Most programs now decode 7z files, and a few will encode them. Why more do not puzzles me. Developer laziness perhaps?

    Realize that the LZMA algorithm has a long way to go before it matches ZIP's flexibility within an OS, for example. It will get there eventually. Like many though, I've been on the receiving end of too many corrupted ZIP files in my life. But for Dwarden below, Squeez handles virtually every format, notably the latest 7z and RAR versions independently. I'm not saying "Squeez is better than 7-Zip"; only that it does far, far more than 7-Zip will ever dream unless IP involves others in its development. There are sound reasons that RAR dominates Usenet, among them is WinRAR's feature set that 7-Zip does not yet provide. Besides, in the next major version, WinRAR will support 7z creation.

    I won't get into the "because it's free, it's better" silliness, because that's what it is and always will be. Price is irrelevant to quality.

    I also think that 7-Zip compresses better than WinRAR. I made some experiments and if the compressed stuff does not contain a lot of multimedia files it is always compressed better when you use 7-Zip.
    7-Zip seems to be slower than WinRAR, but it means less and less because CPUs are faster and faster. My Athlon 64 compresses 700 mb ISO images in around 15-20 minutes (compression: ultra). IMO not bad.

    Moreover, the interface is simple and the app is free. I like it. Thank you, Mr. Pavlov!

Any program that compares its current version to its competitor's 3-year old version is dishonest at most, and misleading at the least. (WinRAR 3.1 was released in the Spring of 2002.) Where was 7-Zip's development three years ago? It's a minor point that seems to have been read and noted by more than 12,000 people in the past month. While I love 7z, 7-Zip has a long way to go unless you're doing only minimal archiving. As a 7z counterexample, check out the German archiver, Squeez.

    demetrisk (below) makes several good points in response to this review, though you seem to begrudge WinRAR because you have to pay for it (for a Lifetime license for all WinRAR products, mind you). That's specious to say the least, and when 7-Zip is measured against programs like WinRAR or Squeez, it demonstrates that 7-Zip is still in its infancy. (And blame that on Igor Pavlov who is in no hurry to develop the program.) My review agrees with you when you say "right for whom?" I think most people who do routine daily or merely personal archiving can get away with 7-Zip as their sole archiver. But it doesn't compare to the more mature feature sets that some of the other archivers provide.

    Does 7z provide better compression? Heck yes, and that's written and graphed a dozen times within, but the undeniably fact is that 7z format is slow, and the surprising fact is that it does not provide a significantly better compression ratio than RAR for large file sets.

    That's it. No controversy there. Test it on a variety of different types of files large and small and see for yourself. Any archiver that does not do 7z creation within the next year will eventually be left behind. 7z extraction will no longer be enough.

    Why anyone would rate this poorly-designed, feature-devoid digital turd highly is beyond me.

    It's free, but that doesn't make it good. Calling this piece of crap the best open-source archiver is like calling Bush the best American president who is currently in office.

    @ zridling: The best open-source award seems meagre to me, to say the least, considering that the only other decent open-source archiver is WiZ, a wrapper for Info-Zip, a program with some nice options, but nowhere near in 7-Zip in zip compression and with no support at all for 7z and rar.

    The DonationCoder review also says this:

    "On its website, 7-Zip deceptively compares the compression ratio of 7z Ultra against WinRAR normal in version 3.1, a three-year old (2002) version. The difference between 7z Ultra to WinRAR Best is statistically insignificant (usually less than 1% difference)."

    It happens that I just uploaded a comparison of just the two formats, 7z and rar. One of the test files was the GIMP directory from Program Files. I used WinRAR 3.50 and 7-Zip 4.26, and the difference in favour of 7z is one percentile more than that given in the 7-Zip home page.

    http://www.kikizas.net/en/apps.7z.html

    The DonationCoder review also claims that TUGZip makes rar archives. AFAIK, this is done by taking Rar.exe from a WinRAR installation and putting it in a TUGZip directory. I'm not sure you are allowed to do this with Rar.exe (UnRar.exe is a different story), even if you have licenced the program.

    As to the essence of the review, WinRAR may be the best archiver overall (but certainly not in terms of compression ratio, where 7-Zip and 7z are stronger), but who exactly it is best for?

    If you just use the format zip, 7-Zip is better than all archivers I have used, and much better than WinRAR (which, however is impressively fast at making zip files).

    File recovery is a great feature of WinRAR, and it will be good when 7-Zip adds this, but, if you don't share files, you will probably never need to recover corrupt rar files. I personally don't do file-sharing and have never come across a corrupt rar.

    Then, 7-Zip does not support in-place editing of solid archives. This is planned, according to the author, but I don't think it is greatly important. For archives that are meant to be edited and updated, just don't use solid compression. It is not meant for this. (The WinRAR Help has a whole page explaining where to use and where not to use solid compression).

    I personally use 7-Zip:
    1. From the context menu to compress and email files or folder, and to compress files, both in the zip and 7z formats.
    2. From the file manager, to browse and edit archives.
    3. From the command line, to keep scheduled incremental backups in the 7z format.

    It does what I want and has never failed me.

    The only thing that annoys me is that it sometimes asks to reboot after updating. This is not fault of 7-Zip, and you can work around it by killing and then restarting explorer.exe, but I think the author of 7-Zip, Igor Pavlov, should do something about it.

    So, in conclusion, who is WinRAR best for, considering all the above and also that the format is proprietary and closed and that the program costs 30 dollars?

    Here is a recent review of 7-Zip, where it won best Open Source archiver. There's an appealing simplicity to 7-Zip, but its author really needs to address its weak, crude interface and build in some more basic features, along with keyboard shortcuts. If you're just doing ZIP and 7z archiving, it doesn't get any easier.

    I've used many archive programs over the years, but for the last two years, only this one.

    I'm sure there are still several others that have glitzier GUI, and more supposedly useful features, but non-glitzy GUI have become a requirement of mine when I consider software, and one man's feature is another's bloat.

    This has all the features I need, supports MORE formats than I'm likely to ever need, and is smaller than most of the others I've tried or seen.

    All this while being free, open-source, and regularly updated. I'm always willing to change software, so I won't ignore something that I think is better for the way I use it, but I've yet to find that something in an archiver.

    7-zip supports a broad range of compression formats; its ZIP support is very fast and efficient.

    It does not have the absolute top compression (which is achieved either by shareware like WinRK or much less user friendly archivers like PAQAR), but the proprietary 7z format gives a good efficiency compromise.

    The interface isn't quite my taste (the shareware WinRAR is better there), but nobody is forced to use it. Otherwise, the program is just great!

    I cannot understand some comments. One could think that adding drag&drop DECREASED the value of the program!

    According to Igor Pavlov, the creator of 7-Zip, a new version of the program that will support both right and left key drag& drop will be released in late July. I guess the mechanisms will be further improved.

    I am not sure if making rars by 7-Zip is really necessary. 7-Zip offers higher compression (in most cases) than WinRAR. 7-Zip opens .rar files. New WinRARs open .7z files. So why bother? 0.02$

    PS 7-Zip has one unique feature that I love. I work with Win 2000 MUI, and 7-Zip automatically changes the language of its interface just as I switch the language of the W2K interface. So if the language is English 7-Zip is also English, if Japanese it is Japanese, if German it is German and if Polish it is Polish. It follows the language version of Windows. No other program does it.

    What you fail to realise is that 7zip has the best compression ratio of any archiver, it uses the lzma format, which is similar to the format used by both winrar and winace but has been extended to allow for greater compression ratios.

    The interface is sparse yes, but the sparseness means it doesn't have useless features which aren't really needed and it doesn't have ads and big newbie friendly buttons.

    The only area I have any complaint over is the decompression of 000 type files. If the set contains a RAR file, the decompression is fine; however, if it does not contain a RAR file (rare), it will decompress the first file in the set and stop. WinRAR is able to recognize that the files are linked and decompress the set as intended.

    As stated, this is a very rare occurence; so, it's no reason for me to stop using 7-Zip. It's a great product, but there's always room for improvement. This is the case with just about any product available.

    The 7z format compresses tighter than RAR in most cases (both formats are easily surpassed by the top programs on www.maximumcompression.com); RAR has a better interface and some good features that 7z lacks, but 7-ZIP is free.

    7z format is good (and so is LZMA) but its NOT a replacement for all those good formats out there! 7z features the best compression only for some files, and good compression for others.

    For compression freaks, or for those who'd like to distribute files over the net, or cramp 1000's of software in a small medium, then compress each file with UHA (I recommend WinUHA), RAR, 7z and check the respective sizes. You'll often find that NO format is absolutely superior than the other.

    7-Zip really rocks! I miss only two things - drag and drop and the decompression of WinACE archives. The new format of compression produces significially smaller archives than any other program, and my Athlon 64 compresses them faster than WinRAR to RAR files. Moreover, the program is for free.

    The GUI's icons are mediocre in my opinion, with a Win95-era look that doesn't compete with modern software. That's a minor complaint and I will still give the program a rating of 5 based on its performance.

    A vastly overrated digital turd. The 7-Zip FORMAT can offer better compression than anything else, on SOME file types, but it's dog slow when it does. The ARCHIVER itself--which, I remind everyone, is what we are rating here--lags behind in features, and has some really stupid design choices inherent to it (extract files > cancel > "Operation aborted" ... Gee thanks, I had no idea what would happen when I clicked "Cancel").

    P.S. The damned uninstaller--a crappy INF file--doesn't even work correctly. The shell extension DLL file and some other junk is left behind. I guess it would have doubled the development time to use a real installer (bringing it right up to 20 minutes or so).

    I can't figure out why, after three major versions, this program still doesn't support drag and drop. You can drag files ONTO the 7-Zip window and create a new archive, but you can't drag files OUT of the 7-Zip window after double clicking and opening an archive. Hardly anyone creates archives by opening the archiver program and dropping files onto it. Everyone just right clicks and "Add to zip/ rar/ 7z/ xyz/ abc/ whatever". So why not be a nice guy and add that feature? IMHO its the only thing - the rest of the app is perfect. Trust me when I say I'm a heavy archiver. ***EDIT*** Whoa .. IZarc rocks. I switched! :)

    I use 7zip quite a long time now, and it is provides the best compression ever seen, almost always better than RAR and ACE. But the best reason for 7zip is that it is really fast at extraction: often 10 times faster than RAR! (rar uses PPMD for text files).

    I use these parameters for maximum compression:
    0=BCJ2 1=LZMA 2=LZMA 3=LZMA b0:1 b0s1:2 b0s2:3 1d=25 2d=21 3d=21 1mf=bt4b 2mf=bt2 3mf=bt2 1fb=255 2fb=255 3fb=255

    with these compression is quite slow, and uses about 350MB RAM, but the resulting files are extremely small and decompession time is very good.

    7-Zip compression is better than RAR imo, but you need to choose 7z as the compression method and not zip. 7-Zip's zip compression gives better zip compression for those that still like to use zip (this is not comparable to RAR compression; 7z compression method is though). What 7-Zip really lacks is multi-volume support (i.e. like with rar you have r01, r02, etc or part1, part2, etc). If you need multi-volume support then use WinRAR; otherwise, use 7z compression method for better compression results in general.

    I like it and have used it for two weeks and have a few suggestions: speed it up, not nearly as fast as WinZip on my computer, normal mode is nice but maximum doesn't seem to do much extra compression, it's real finicky about which files it will do well with, even though it is even slower, maximum should make a noticable difference.

    I'm a pupil and so I can use a good PACKER with a nice GUI; it can work with the most archive-types - Thanks for this.

    When compressing uncompressed files, the 7Zip format tends to give slightly better compression ratios than RAR. However, when compressing multimedia files (such as MP3s or JPEGs) or compressed files (such as a self-extracting EXE), 7Zip's archive will actually be *larger* than the original file, while WinRAR's RAR archive will always be at least slightly smaller. This is a pretty major shortcoming.

    First i'm a 7-zip user.. and i'm an ARCHITECT not a programmer.. i used 7-zip in my work.. and because i liked much i provided an ARABIC language support to it..
    MAAD is the first letter of my full name.. Deeb is my family name .. so i'm realy forwared .. theres is nothing to hide.. while i was an architect student i used in my university some compression tool for my large size (in reality and in MB) to reduce it to FLOPPIES.. Floppies i went from arc,ha,zip,cab,rk,rar,ace,...till i found 7-zip..
    7-zip for me made work much easier ... i even updated my stored university work to it.. i like very much .. and if like something very much you recommend it to others .. if i say wrong then correct .. for your information QuickZip has supported 7-zip format (i use quickzip because it can decompress older formats and can handel new ones) .. ask them is it a bad compression format or not... and don't forget that 7-zip is still in beta not even released.. and if you learned more information about 7-zip author you would donate money for him as IGOR PAVLOV was also the author of many well known old compressors.. so why not help him .. even more he mad 7-zip an open-source project is this wrong.. so any one can help should help him so 7-zip get better and better..again i'm an ARCHITECT not a programmer .. i can design any building you like but not code a single programming line.. BTW i'm from JORDAN

    It is going better and better.
    The new beta 21, improves the compression speed.
    Decompression speed was improved in beta 20.
    Compression ratio has been always excellent.

    Now it only needs to add some features

    The previous post is very suspicious. "maad deeb" is probably a handle used by the program author - just read the January 11th, 2002 6:12 AM post.

    I think it's pretty pathetic when program authors stoop to suck tactics in order to plug their own warez.

    I like it. It's not really complete for unarchiving (no ACE) so I also have WinACE installed but one day, if development continues at the rate it has, I'll just use this :)

    Reviewing 2.30 Beta 10 (Jan 11, 2002)

    7-zip is Super archiver .. why becuase other compressors are old.. even ACE v2.0 .. 7zip outform ace_v2.0 on 95% cases with the cost of "FREEWARE".. it is now localized to 8-languages..(for ace you have to download more MB's for each new lang.) and 7-zip is is small (0.86Mb) not like ACE..(2.5MB) so 7-zip can be combined nearly any where..

    further more the 95% can be increased with some more settings and few more time..and it can reach 99%..(for now at the moment)

    and last a very important thing to cosider which compressor is better..
    compression makes too many calculations..
    decompression makes few calculations..

    so zip is famous because it decompress faster and compre it with RAR and ACE and 7z you will notice that 7z decompress as fast as zip do ... so buzz off ACE..
    if you want to truely combare compression .. combare 7zip with CAB (it has tighter compression than ACE but it eats up time)

    I must say, this is by far the BEST compression I have seen to date. I tested 7-Zip out against all the other formats I have available for common useage. As the example, I used a 157KB exe file that I had built. Zip brought it down to 56, same LZH, Tar was aweful, and the only comparable format was BH (46KB). 7Zip rocked the competition with 43KB. The only problem I could ever think of is that this format is not used enough!!! boy I wish more companies employed this when they send their software out.

    The best on 7zip is that it can handle unix file formats such as tar, gzip and bzip2

    Tested 7-zip .. I think this program does good job by squeezing files in 7z format more than zip format. I tried images and other files found out that it's best when compressing non compressed format like BMP images TXT DOC and much more , but found very equal to ZIP when compressing JPG ,Note: in all the test I used maximum compression . I will give 5 , it's power and free ..

    Yes, I know that Power Archiver is now shareware. It's well worth it, so I registered. :-) As for 7 Zip, it has a way to go. It's good for non-power users, and serves a definite purpose. It will become as good as PA some day and will go SHareware too. :-) (bobad@charter.net)

    "Certainly is interesting how they integrated zip files into Explorer, but I've heard that Windows XP will do that automatically anyway. Why bother?"... Replace "zip files" with "web browsing", "listening to MP3s", or "writing CDs" and you've actually summarized Micro$oft's marketing strategy PERFECTLY. "Why bother?" indeed... perhaps to make sure someone other than Bill Gates gets a break?

    If you don't already have a zip program, sure, I guess this one will do alright. Certainly is interesting how they integrated zip files into Explorer, but I've heard that Windows XP will do that automatically anyway. Why bother? I had hoped the increased compression rate would turn the tide though (versus WinZip), and yet again, no... same sizes on Max compression for large (18 MB, for example) files. Oh well!

    7-zip has the best .zip compression ratio of all.Better than winzip and power archiver and all the others.It's real it can compress 10%-20% more than the others.mThe explorer integration is still buggy..but i use power archiver for unzipping or checking the packed files..and 7-zip for compressing them.

    Actually, this program is marked shareware, but is in fact free. (You know, if you are going to try out someone's program, you should at least vsit their website first before you make blatantly wrong remarks about it.) I have been using 7-zip for a few months now and have to say that it is any excellent program, has windows integration that works (it doesn't matter if it doesn't pop up in the same window, that is not what is meant by windows integration, but instead that the program opens when you double click on the file, which it does, and that it recognizes files when you right click them as to whether they are a zip file, or files to be archived.) Also, you have to understand that this is a beta version, and if you don't like betas, he have his newest final version on his website, version 2.24. Finally, this program DOES unzip files, but what it is mainly meant for is its excellent zip compression ratios, and other compression formats, which it by far does very well. Some of this programs best features is that it is small, it can be run simply by selecting the files, right-clicking them, and selecting its "Add to Archive" option, and that it will name the final zipped arhive to that of the directory the original files are located in, unless you choose otherwise. Again, excellent program, and remember people, this site is not called "Beta"News for nothing.

    The only archive program that has FULL shell integration is Power Archiver, and it's FREE. I just don't get it. How can anyone expect people to buy software when there are better programs that are totally free? Power Archiver has an "Extract Here" for single and MULTIPLE ZIP's, which no other program has. It also has an EXTRACT HERE, which is very useful to Explorer users. It also unzips RAR and ACE with a right click. Winace, WinRAR, WinZip, 7Zip, and the rest need to get a clue about Power Archiver's awesome shell integration.

    I thought the program was integrated fairly well. I haven't used a wide variety of archivers but I have used the two most popular. WinZip and PKZip.

    I did a comparison archival of a BMP file I had with WinZip VS 7-Zip. WinZip was 518k 7-Zip was 451k which is a decent margin and well within the 2-10% the program claimed. I then tried a few other formats offered and found BZip2 format to be the best for condensing the BMP file down to a low low 330k.

    It DID open files with a double click for me. Inside that if I double clicked the appropriate file (my BMP) it allowed me to view it.

    Archiving was done with a right click and then "add to archive" at which point a simple menu asking archive format and level of compression appeared. Seemed pretty clean to me.

    I then tried to zip up a JPG version of the same BMP. At which point windows explorer crashed ;-) I don't know if that is related yet. And this is a BETA afterall.

    The ratio of compression, number of formats supported, and the ease of use impressed me overall.

    This program is the worse program I have every used.
    They write it's integrated into the windows shell, well, the last this I would say it that it's integrated. When you open archive in Windows Explorer it's open new window, when you double-clicked a file it's doesn't open it.
    It's does nothing right, you better use WinRAR or PowerArchiver 2000.
    This program need a lot of work to be done!
