7-Zip is an open source file archiver with the high compression ratio predominantly for the Microsoft Windows operating system. It operates either as a command line program or with a graphical user interface.
It also features integration with the Windows shell environment. 7-Zip is free software, developed by Igor Pavlov and distributed under the GNU LGPL license. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip.

FEATURES
• High compression ratio in new 7z format with LZMA compression
• Strong AES-256 encryption in 7z and ZIP formats
• Self-extracting capability for 7z format
• Integration with Windows Shell
• Powerful File Manager
• Powerful command line version
• Plugin for FAR Manager
• Localizations for 74 languages
• Supported formats:
– Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
– Unpacking only: RAR, CAB, ISO, ARJ, LZH, CHM, MSI, WIM, Z, CPIO, RPM, DEB and NSIS
NEW
* 7-Zip File Manager now can operate with alternate file streams at NTFS volumes via “File / Alternate Streams” menu command.
* 7-Zip now can extract .zipx (WinZip) archives that use xz compression.
* new optional “section size” parameter for BCJ2 filter for compression ratio improving. Example: -mf=BCJ2:d9M, if largest executable section in files is smaller than 9 MB.
* Speed optimizations for BCJ2 filter and SHA-1 and SHA-256 calculation.
* Console version now uses stderr stream for error messages.
* Console version now shows names of processed files only in progress line by default.
* new -bb[0-3] switch to set output log level. -bb1 shows names of processed files in log.
* new -bs[o|e|p][0|1|2] switch to set stream for output messages; o: output, e: error, p: progress line; 0: disable, 1: stdout, 2: stderr.
* new -bt switch to show execution time statistics.
* new -myx[0-9] switch to set level of file analysis.
* new -mmtf- switch to set single thread mode for filters.
* The BUG was fixed: 7-Zip didn’t restore NTFS permissions for folders during extracting from WIM archives.
* The BUG was fixed: The command line version: if the command “rn” (Rename) was called with more than one pair of paths, 7-Zip used only first rename pair.
* Some bugs were fixed.
