'''WAD''' (which, according to the [[Doom Bible]], is an acronym for "Where's All the Data?"[http://5years.doomworld.com/doombible/doombible.pdf]) is the file format used by Doom and all Doom-engine-based games for storing data. A WAD file consists of a header, a directory, and the data that makes up the resources stored within the file. WADs can be either [[IWAD]]s or [[PWAD]]s.
