7-Zip

March 18, 2009

7-Zip unpacks most archive formats, including ZIP, TAR, GZ, RAR, and its own 7z format. It can create TAR and GZ archives, which are commonly used on Unix and Linux systems. In our tests, 7z archives were up to 40 percent smaller than their ZIP equivalents, although compression did take longer. Advanced options include the ability to create solid and self-extracting archives, and to adjust the compression level and password protection. The program also has a command-line module.

Though the main interface is overly simple, it’s easy to use and self-explanatory. The context menu options indicate that 7-Zip should be taken seriously.
