7-Zip is an open source file archiver designed originally for Microsoft Windows. 7-Zip primarily uses the 7z archive format, and can also read and write to several other archive formats. The program can be used from either a command-line interface, graphical user interface, or Windows shell integration. 7-Zip began in 1999 and is actively developed by Igor Pavlov. It is related to a cross-platform port, p7zip.

7-Zip is distributed under the GNU Lesser General Public License. It was the winner of the 2007 community choice awards for "Technical Design" and for "Best Project".

Supported formatsEdit

Some of the formats that 7-zip can open only go one way (i.e. it can read and extract the contents of the archive, but cannot add files to the existing archive, nor create one of that type). For ZIP and GZIP compression, 7-zip claims to support a 2-10% higher compression ratio than either PKZip or WinZip.
