Fictional file formats

These file formats actually do not exist, but this is just for fun and reference. These include electronic file formats from movies, games, tv, sci-fi, etc. (Sometimes people actually create working implementations of them after the fact; in those cases, the actual versions can be documented in the appropriate category for real file formats, with a cross-reference here about the fictional version.)

See also Fictional physical formats, as well as the "fictional" constructed languages in Spoken Languages.
