MWD

The MWD is an archive file used in fifth generation era SCEE Cambridge Studio games. The MWD would usually hold the majority of a game's resources, including textures (VLOs), models (MOFs), sounds (VHs/VBs), and more.

Etymology
It is believed that MWD stands for MediEvil WAD or Millennium WAD. The acronym WAD was coined during the development of Doom and stands for Where's All the Data?
