By default, all software supports multiple file extensions. R:BASE supports at least 3 different file extensions. The basic files that R:BASE supports are .RB1. However, not all of the extensions listed on the list are always used to save the effects of work in R:BASE. Very often, files with such extensions are used as source data files used by R:BASE.
R:BASE 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 R:BASE and try to save it in another file format, also supported by R:BASE.
