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.

An excellent archive tool 5 stars by iwillneverstop Jan 07, 2013 (Read all my 21 reviews)
I don't know that this tool supports a lot of archive formats that are popular in other OSs than MS Windows such as DMG, XAR in Mac OS, Deb in Linux until I need to write an tutorial of how to extract content from a file (.dmg) which is actually in XAR format. From that, I see 7-zip as an excellent archive tool. I highly recommend it for cross-platform users. show Review details

Competent, effective, blazingly fast 5 stars by gwestbound Dec 02, 2011 (Read all my 19 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. show Review details
