Supported formats — Packing / unpacking: 7z, ZIP, GZIP, BZIP2 and TAR. Unpacking only: 7z, ZIP, RAR, GZIP, GZ, BZIP2, BZ2, TAR, CAB, ISO, ARJ, LZH, LHA, CHM, MSI, WIM, Z, CPIO, RPM, DEB, CPIO, DMG, FAT, HFS, LZMA, NTFS, SPLIT, SWM, TAZ, TBZ, TBZ2, TGZ, TPZ, VHD, XAR, XZ, Z 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. Localizations for 70 languages.

Features

The main features of 7-Zip:
  • High compression ratio in 7z format with LZMA and LZMA2 compression
  • Supported formats:
  • Packing / unpacking: 7z, XZ, BZIP2, GZIP, TAR, ZIP and WIM
  • Unpacking only: AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VMDK, WIM, XAR and Z.
  • For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 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 87 languages

7z has an open architecture, so it can support any new compression method, too. The following methods currently are integrated into 7z:
  • LZMA — Improved and optimized version of LZ77 algorithm
  • PPMD — Dmitry Shkarin's PPMdH with small changes
  • BCJ — Converter for 32-bit x86 executables
  • BCJ2 — Converter for 32-bit x86 executables
  • BZip2 — Standard BWT algorithm
  • Deflate — Standard LZ77-based algorithm

LZMA is the default and general compression method of 7z format. The main features of LZMA are:
  • High compression ratio
  • Variable dictionary size (up to 4 GB)
  • Compression speed: about 1 MB/s on 2 GHz CPU
  • Decompression speed: about 10-20 MB/s on 2 GHz CPU
  • Small memory requirement for decompression (depend from dictionary size)
  • Small code size for decompression: about 5 KB
  • Supports multi-threading and P4's hyper-threading


Changelog

  • Encryption strength for 7z archives was increased:
  • the size of random initialization vector was increased from 64-bit to 128-bit, and the pseudo-random number generator was improved.
  • Some bugs were fixed.
