By default, all software supports multiple file extensions. TrackMania supports at least 2 different file extensions. The basic files that TrackMania supports are .GBX. However, not all of the extensions listed on the list are always used to save the effects of work in TrackMania. Very often, files with such extensions are used as source data files used by TrackMania.
