ARJZ is a compressed archive utility, primarily developed by Bulat Ziganshin (Булат Зиганшин). Its native file format is an incompatible variant of ARJ.

[edit] Format details

ARJZ's main features seem to be:

  • Increase ARJ's 26K history window to 32K, like LHA's "lh6" method. Indicated by ARJ's minimum archiver version to extract field set to 50.
  • Increase the history window to 64K, like LHA's "lh7" method. Indicated by ARJ's minimum archiver version to extract field set to 51.
  • Some sort of audio-targeted compression technique, enabled by the -t9 option. Indicated by ARJ's "file type" field set to 9.

[edit] Identification

Like ARJ, an ARJZ file starts with bytes 0x60 0xea, and has 0x02 at offset 10.

Unlike ARJ, ARJZ files are observed to have 0x33 at offset 5 (meaning archiver version = 51).
