7-Zip a great WinZip alternative

7-Zip from is a great open source software for handling zip files as well as other formats. One I have found use for is to extract the contents of ISO files.

The main features of 7-Zip

  • High compression ratio in new 7z format with LZMA compression
  • Supported formats:
    • Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR
    • Unpacking only: RAR, CAB, ISO, ARJ, LZH, CHM, Z, CPIO, RPM, DEB and NSIS
  • For ZIP and GZIP formats 7-Zip provides compression ratio that is 2-10 % better than ratio provided by PKZip and WinZip
  • Self-extracting capability for 7z format
  • Integration with Windows Shell
  • Powerful File Manager
  • Powerful command line version
  • Plugin for FAR Manager
  • Localizations for 63 languages

    Been using 7-Zip for a while now. I have a machine that emails me log files in ZIP format, the log file is nested 3 folders deep in the ZIP. One of the folders has a 'blank' name (no idea why) ... anyway, the built in ZIP functionality in Windows XP chokes on the "blank" folder name... 7-Zip works great.
