7-Zip is an open source file archiver designed originally for Microsoft Windows, and later made available to other computer operating systems. Later 7-Zip has been ported for use on Unix-like systems such as GNU/Linux, BSD, and Mac OS X. It is also compatible with DOS via either a DOS port, or by using the HX-DOS extender to run the Windows command-line version.
7-Zip operates primarily with the 7z archive format, as well as being able to read several other archive formats. Supported formats include ZIP, Microsoft cabinet (CAB) files, RAR, ARJ, Z, gzip, bzip2, LHA, tar, cpio, rpm and Debian deb archives. Versions of 7-Zip from 4.42 onwards also support ISO CD/DVD images.
In contrast to the market-leading programs WinZip and WinRAR, which remain as proprietary competitors, 7-Zip is distributed under the terms of the GNU Lesser General Public License (LGPL) (with the RAR license restrictions).
