By default, all software supports multiple file extensions. Starcraft supports at least 2 different file extensions. The basic files that Starcraft supports are .MLX. However, not all of the extensions listed on the list are always used to save the effects of work in Starcraft. Very often, files with such extensions are used as source data files used by Starcraft.
Starcraft 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 Starcraft and try to save it in another file format, also supported by Starcraft.
