Quick Link: 7-Zip 4.47 in Beta
7-Zip is a rock-solid file archiver for Windows with a high compression ratio. It is the premier archiver for the LZMA compression format (a.k.a. 7z). Indeed, the 7-zip web site is also the home of the LZMA SDK (Software Development Kit).
Version 4.42 of 7-zip has been a workhorse for over a year. The just-released 4.47 (beta) offers these improvements:
- New fast compression mode for Deflate method in Zip and GZip.
- New “Compress shared files” option in GUI and -ssw switch.
- Some bugs were fixed.
- New localization: Norwegian Nynorsk.
The main features of 7-Zip are:
- 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 a compression ratio that is 2-10 % better than the 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
