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