PAK (ARC extension)
PAK is a DOS utility for managing compressed archive files, developed by NoGate Consulting. It is also the name of one of the file formats it supports: .PAK format.
PAK format is an extension of ARC format. The differences are that it may use some PAK-specific compression methods (#10 "crushed", and #11 "distilled"), and that it has some features made possible by "extended records" stored after the end-of-archive marker.
PAK was originally named GSARC (and used filename extension .ARC), but was quickly renamed to PAK (and the default extension changed to .PAK).
See PAK for more formats named PAK.
The PAK.DOC file contained in the v2.51 distribution includes basic information about .PAK/.ARC format, including the extended records. It does not document the compression schemes in detail.
