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