ZPAQ archive format

ZPAQ is an open source archving program developed by Matt Mahoney and also is the filename extension of an archive created by the program.

Unlike other common archive formats including ZIP, 7Z, and RAR, the ZPAQ format is a journaling format which can save both the old and new versions of an archive.
