What is a PAK file?
A PAK file is an archive used by video games such as Quake, Hexen, Crysis, Far Cry, Half-Life, and Exient XGS Engine games. It may include graphics, objects, textures, sounds, and other game data "packed" into a single file. PAK files are often just a renamed .ZIP file.
More Information
PAK files are primarily used by video games but may also be used by other applications such as the Google Chrome web browser. The format for a PAK file used by one game may differ from the PAK format used for a different game. Therefore, you may have to try multiple programs before opening your PAK file.

A PAK file may also be a resource package used by the video game Starbound. It contains images, audio, cinematic, and configuration files. Starbound loads resources from its PAK files when players play the game.
More Information
Starbound is a 2D space exploration game published by Chucklefish. It is available for Windows, macOS, and Linux.
In 2014, with the release of the Furious Koala update, Starbound began using resource packages saved as PAK files. These packages store files the game references and uses during gameplay. For example, PAK files contain in-game images, audio, and cinematics, as well as configuration files that control gameplay.

How to open a PAK file
You can use PAKit (multi-platform) to extract a PAK file's contents. You can also use PAKit to pack files into a new PAK file.
