7-Zip is an open source file archiver designed originally for Microsoft Windows. 7-Zip operates primarily with the 7z archive format, as well as being able to read and write to several other archive formats.
Unlike WinZip and WinRAR programs, which are distributed under proprietary licenses, 7-Zip is distributed under the GNU Lesser General Public License.
7-Zip supports a number of other compression, and non-compression, archive formats. Supported formats include ZIP, Microsoft cabinet (CAB) files, RAR, ARJ, Z, gzip, bzip2, LHA, tar, cpio, smzip, JAR, rpm and Debian deb archives. Versions of 7-Zip from 4.42 onwards also support ISO CD/DVD images.
