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