By default, all software supports multiple file extensions. Diablo supports at least 4 different file extensions. The basic files that Diablo supports are .MPQ. However, not all of the extensions listed on the list are always used to save the effects of work in Diablo. Very often, files with such extensions are used as source data files used by Diablo.
Diablo can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via Diablo and try to save it in another file format, also supported by Diablo.
