By default, all software supports multiple file extensions. 3D Slicer supports at least 1 different file extensions. The basic files that 3D Slicer supports are .MRML. However, not all of the extensions listed on the list are always used to save the effects of work in 3D Slicer. Very often, files with such extensions are used as source data files used by 3D Slicer.
3D Slicer 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 3D Slicer and try to save it in another file format, also supported by 3D Slicer.
