7-Zip is a program for creating or unpacking archived and compressed files in an enormous variety of formats.

7-Zip can both create or unpack the following formats: 7zip, ZIP, CAB, RAR, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB files. For the standard ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2 – 10 % better than that provided by PKZip or WinZip, and the native 7zip format can provide a 45% reduction in file size from the common zip format.

The program is highly configurable, allowing the user to balance the level of compression and speed. The interface is designed to mimic the standard Windows shell, Explorer, and is localized to 40 languages.
