open-source file archiver 7Zip is an open-source file archiver, that offers a the highest compression ratio, using the new f 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). In addition, 7Zip also supports 7z, ZIP, CAB, RAR, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB formats, so it can be used with all popular archive files as well. The program offers a basic file explorer interface and also integrates into the Windows right-click menu. You can associate 7zip with any of the supported formats and also offers command-line support. Interface and additional features are fairly basic, but the compression ratio is outstanding.

Competent, effective, blazingly fast 5 stars by gwestbound (Read all my 16 reviews)
Look no further. 7-Zip is a small, clean, neat, effective, fast, zip program. Doesn't load your computer up with crapware, like Facebook links and donation nag screens. Just does it's job - fast! Bonus: it's also a basic file manager. showShow review details
Simple and fast 5 stars by Keysmith (Read all my 4 reviews)
It is freeware open-source and good. Fast load/open, drag n drop and right-click shell integration. It opens large number of formats ZIP, 7Z, RAR, etc but only compresses to 2 major (zip and 7z) and some minor (linux found such as tar etc). 7z is starting to get more and more famous and it is quite efficient as well (even better than rar). Only downside, I would prefer if it could compress RAR archives (it only extracts them). showShow review details
