7z is a file format for archiving and data compression, developed by Igor Pavlov. It is the native format of the 7-Zip archiving application.

Contents

[edit] Format details

The 7z format defines many compression methods. The ones normally used are LZMA2 (default for 7-Zip 9.30 alpha ), LZMA (default for 7-Zip prior to 9.30 alpha), PPMd, and bzip2.

[edit] Identification

7z files begin with signature bytes '7' 'z' BC AF 27 1C.

[edit] Related formats

  • S7z
  • UFA (predecessor?)
  • 777 (predecessor?)
  • BIX (predecessor?)
  • ARG (same author)

[edit] Specifications

  • Refer to the DOC/7zFormat.txt and DOC/Methods.txt files in the source distribution.

[edit] Software

  • 7-Zip
  • 7zX for Mac
  • p7zip
  • Radyx - creates 7-zip archives using only the LZMA2 compression algorithm provided by the Fast LZMA2 Library
