7-Zip is a file archiver that was developed for computers running Microsoft Windows. It uses the 7zfile format, which ensures higher level of compression (up to 50% higher than the standard zip format), but can easily work with other formats as well.

The Adobe AIR, runtime enables you to have your favorite web applications with you all the time. Since applications built for Adobe AIR run on your desktop computer without a web browser, they provide all the convenience of a desktop application.

Key Features of 7-Zip:

  • High compression ratio in new 7z format with LZMA compression
  • Supported formats: Packing / unpacking: (7z, ZIP, GZIP, BZIP2 and TAR) and Unpacking only: (ARJ, CAB, CHM, CPIO, DEB, DMG, HFS, ISO, LZH, LZMA, MSI, NSIS, RAR, RPM, UDF, WIM, XAR and Z.)
  • For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than theratio provided by PKZip and WinZip

  • Self-extracting capability for 7z format
  • Integration with Windows Shell
  • Powerful File Manager
