777 and BIX format is an experimental version of this. UFA imported many features from 777. The differences between 777 and UFA:

  • Some compression methods are different(normal, sound, bitmap, executables).
  • On Win32 x86 executables, 777 can compress better than UFA, but it takes more times to process.
  • UFA can process more faster than 777.

However, UFA is not updated after the first version of BIX is published, not like 777. BIX's improvement are imported to 7z format.
