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.

Format details

7z supports several compression schemes:

Identification

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

The 7-Zip software will automatically find embedded 7z data in many cases (but apparently not if the file extension is .7z). This makes it possible to create hybrid files that look like some other format, but which will be interpreted as 7z format by 7-Zip.

Related formats

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

Specifications
