The format specifies a multimedia container file that contains one or more tracks, each of which stores a particular type of data: audio, video, or text (e.g. for subtitles). Each track either contains a digitally-encoded media stream (using a specific format) or a data reference to the media stream located in another file. Tracks are maintained in a hierarchical data structure consisting of objects called atoms.

The DPG file is a container file format that allows a user to play movies on the Nintendo DS gaming system. These DPG movies can also be played on computers if the computer user has installed a DPG-compatible media player. The Windows application manager also uses the .dpg file suffix. These DPG files contain program group files that have been deleted with the application manager.
