You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.

The main features of 7-Zip are:

  • High compression ratio in new 7z format with LZMA compression
  • Compression ratio for ZIP and GZIP formats: 2-10 % better than the ratio provided by PKZip and WinZip
  • 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

Changes in 7-Zip 17.01 Beta:

  • Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
  • 7-Zip now uses additional memory buffers for multi-block LZMA2 compression. CPU utilization was slightly improved.
  • 7-zip now creates multi-block xz archives by default. Block size can be
  • specified with -ms[Size]{m|g} switch.
  • xz decoder now can unpack random block from multi-block xz archives. 7-Zip File Manager now can open nested multi-block xz archives. (for example, image.iso.xz) without full unpacking of xz archive.
  • 7-Zip now can create zip archives from stdin to stdout.
  • 7-Zip command line: @listfile now doesn't work after -- switch. Use -i@listfile before -- switch instead.

Fixed bugs:

  • 7-Zip could add unrequired alternate file streams to WIM archives,
  • for commands that contain filename wildcards and -sns switch.
  • 7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.
  • 7-Zip 17.00 beta ignored "Use large memory pages" option.
