7-Zip is an open source file archive intended initially for
Microsoft Windows which can be used freely. It is distributed under the
GNU Lesser General Public License. 7-Zip was zealously established by
Igor Pavlov and was begun in the year 1999. The SourceForge.net 2007
community choice awards awarded 7-Zip as the victor for "Technical
Design" and "Best Project". As 7-Zip functions with the 7z archive
format, it can interpret and write down several new archive formats.
This program can be used from a command line interface, graphical user
interface, or Windows shell integration.
