jalaffa Posted May 2, 2009 Share Posted May 2, 2009 7Zip is an open-source file archiver, that offers the highest compression ratio, using the new 7z format, which delivers compression results that are usually 30-50% better than standard ZIP. We tested it with a server log file, which compressed with ZIP had a file size of 18 mb and using 7-Zip was reduced to 8 mb (results may vary, depending on file type). 7Zip supports 7z, ZIP, CAB, RAR, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB formats, so it can be used with all popular archive files. The program offers a basic file explorer interface and also integrates into the Windows right-click menu. It can be associated with any of the supported formats and also offers commandline support.Download Link to comment Share on other sites More sharing options...
