By default, all software supports multiple file extensions. StarCraft II supports at least 17 different file extensions. The basic files that StarCraft II supports are .MFIL. However, not all of the extensions listed on the list are always used to save the effects of work in StarCraft II. Very often, files with such extensions are used as source data files used by StarCraft II.
StarCraft II 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 II and try to save it in another file format, also supported by StarCraft II.
