By default, all software supports multiple file extensions. MS-DOS supports at least 39 different file extensions. The basic files that MS-DOS supports are .EXE. However, not all of the extensions listed on the list are always used to save the effects of work in MS-DOS. Very often, files with such extensions are used as source data files used by MS-DOS.
MS-DOS 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 MS-DOS and try to save it in another file format, also supported by MS-DOS.
