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