“A PAK file is an archive used by video games such as Quake, Hexen, Crysis, Far Cry, and Half-Life. 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.”
“A VPK file is a Valve Pak file used by some games developed with the Source Engine.”
So please add, these:
.pak #Game Data Packed File
.vpk #Valve Packed File
