ADFS has continued in use on Risc OS computers, progressing to the 3.5 inch 800k and 3.5 inch 1.6Mb formats used by modern Risc OS computers. ADFS drives as used on Risc OS computers can also by default read and format all standard DOS and Amiga discs and (with a little 16k software thingy) read and format all standard Mac discs.
