7-Zip Compressor like Winrar

7-Zip is an open source file archiver designed originally for the Microsoft Windows operating system, and later made available to other systems. In the form of p7zip, 7-Zip has been ported for use on Unix-like systems such as Linux and FreeBSD. 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 7z archive format, as well as being able to read several other archive formats. In operation a user is free to use command line (all systems), graphical user interface ("Windows" only) or seamless MS Windows shell environment methods of control.

7-Zip began in 2000 and is actively developed by Igor Pavlov. It is distributed under the terms of GNU Lesser General Public License (LGPL). As free software the program is free to share and comes with modifiable source code in contrast to the market-leading programs WinZip and WinRAR, which remain as proprietary competitors. Note that 7-Zip still uses a proprietary plugin to read RAR archives.
