Quake .pak is the container file format for storing game assets in versions 1 and 2 of ID Tech game engine and some derivatives of it, including following games:

Later Id Tech games (starting from Quake 3/ID Tech 3) switched to ZIP format with .pk3 extension.

Description

This file format is very simple. File starts with PACK magic string (4 octets), then 4-byte offset to file table and 4-byte length (measured in bytes) of it.

File table consists of entries consisting of:

  • file contents offset (from beginning of .pak file), 4 bytes
  • file contents length

All numbers are little-endian.
