'''D3TV''' files are game data files used by the v3.x of the D.U.N.E (Developers Universal Non-programming Environment) Engine, which added support for CD Audio with the Commodore CDTV. These files usually correspond to individual "shots" in a DUNE game, and are based on the [[IFF]] metaformat.

== Identification ==
D3TV files begin with <code>FORM</code>, have the file-size in bytes starting at offset 4, and have a type indicator of <code>D3TV</code> at offset 8.

== Chunks ==
These files contain many different chunks for different types of game data. All offsets mentioned are relative to the start of the chunk identifier.
