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...

Love it! 4.58 beta 2008-05-05 ------------------------- - 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.

Best free archiver. I use both it and WinRAR on all my PCs.

When compressing it uses 100% CPU and makes other applications unresponsive, unless I click on Background button.
