7-Zip (a real alternative of Winzip and Winrar) is open source software which works in Windows 7 / Vista / XP / 2008 / 2003 / 2000 / NT / ME / 98. Use this free soft to compress or decompress your files in all the extentions (eg. .zip, .rar, .tar, .cab etc...).
There is a port of the command line version to Linux/Unix. Compression ratio results are very dependent upon the data in the file. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. And 7-Zip compresses to zip format 2-10% better than most of other zip compatible programs.
