Publisher's Description

UltraDefrag is powerful Open Source defragmentation tool for Windows NT. It is very fast, because the defragmenting is done by kernel-mode driver. They are three interfaces to them: graphical, console and native. The GUI is very useful, because it represents your filesystem visually as a color coded cluster map. The console is another option for those that prefer the command line. It allows you to run UltraDefrag from the task scheduler and scripts.

Extremely unimpressive program. Ran a full defrag with it on one of my drives which was mostly defragmented to see what it would do. It started pulling data and writing it to the END of the disk, leaving 50% alone and moving 50%.. continued on like that, doing nothing else, for about ten minutes. When it was halfway completed I quit out. I don't know what it was going to do after it finished, but a regular defragmenter analyses data and moves it if necessary. MyDefrag placed the data properly, and doesn't do a massive amount of work on already-close-to-defragmented drives. Avoid this program, the defrag algorithm looks pretty useless.

faster is NOT better..... I can do an 8 hour defrag with o&o defrag and the results are amazing

"- The Explorer context menu is now reduced to a single entry with sub-menu on Windows 7 and above"

How about an option to NOT have context menus during install. Guess that would be asking for too much. Good thing there's no real reason for me to update to this version.
3 1/2 stars

A very nice update to a good little utility.

All Day? This is one of the fastest defrag utilities I have ever used and this version is faster than the last.

Keepsgetting better and better. I like to use this from safe mode with command prompt for a thorough defrag.

Tried in the past and didn't think much of it. Has improved much since. However, did not detect my USB keyboard on boot-time scan(was supposedly fixed in version 5.xx). Default context menu insertions are overly ridiculous, but I got rid of them easily via regedit.
3 1/2 stars..... 4 stars when the USB keyboard problem is finally fixed, if it's even fixable.
UPDATE: My bad, the keyboard IS seen on boot-scan startup. 4 star program.

A good update to a very nice little utility. Finding the 64 bit version is a bit of a chore. But over all a definite 5 star pick.

I have been a fan of Piriform's Defraggler for quite a while, but after reading the reviews on this I figured I'd give it a try. This version would not work on my Win 7 64 bit system. I did a little scrounging around and found the 64 bit version, installed it and was pleasantly surprised. A very nice little utility.

All you need: It does the job of defrgging very well ~ If you want however a fancy interface, unnecessary services running in the background & prefer to pay there are commercial defraggers that do the job just as well.

Works very well and constantly updated. I wish that the devs would take those square brackets out of the context menu settings though. They make the context menu look untidy.

Still as good as PerfectDisc 12.xx & better & faster than O&O 11.xx, & still free, keep up the good work.

BTW - PefectDisc actually is designed to give the illusion of a perfectly un-fragmented disc. And as a solid state disc at the very least for boot-up (which is pretty much ideal for the time being) the days of pay for defraggers has gone. They ought to be thinking up new software or be out of a job.

Also any speed gains that O&O & Raxco give is removed by having services running in the background which is pretty stupid.

I am confused at the results spectrum I see here - if you are replacing the Windows defrag utility, then why is it being used to benchmark this utilities effectiveness? In my environment, I have several machines allocated for different tasks, as well as a main fileserver.The client machines are all Win7 Enterprise 64-bit, and the server is Server 2008 R2 64-bit. I have used, Defraggler, O&O, Diskeeper, SmartDefrag (formerly MyDefrag), and Auslogics. Ultradefreag comes in a strong first place in two categories: 1. Speed of file access and application startup 2. Speed of full optimization and boot-time defrag. This hold true on server as well as workstation tests. I have a multimedia studio, and the files are many, constantly changing content, size and location (all workstations have at least 3 internal drives - server has 6) The other area this utility shines in is optimizing media files well in excess of 1GB. I can do a typical 1TB full optimization in less than 5 minutes (it is done daily on all machines), and the subsequent file access times are slashed from all other tested defragmenters.The application startup time, and plugin render times on the DAW and Video machines is beyond a simple improvement - it is on the order of 1/4 the previous times. I have not bithered to see what any other defragmenter says about fragmentation - when I used their algorithms, the times were nowhere near what they are now, so my opinion is those are the flawed algorithms, not Ultradefrag's algorithms. This has been an ongoing test - for years, but with the release of v5 RC1, Ultradefrag has moved into the big league. I can not express my gratitude for this wonderful, and FREE program - many, many thanks - keep up the good work guys!
