My Grandmother has a cd player in her home which only reads cds with the cdfs (Compact Disc File System). And my Grandfather likes to make backup copies of all their audio cds, just so the original doesn't get ruined. Although, he can't find a way to burn a cd using the cdfs, on his computer, it only allows udfs (Universal Data File System).
So I'm wondering how to burn a cd with the cdfs format. If anyone knows how, hopefully without use of excess burning software, please tell me how. Btw, he is running Windows 7. Thank you for your time.
