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