CDFS, or Compact Disc File System, is a type of file system used to burn data onto CDs. The main advantage of using the CDFS file system is its compatibility with a wide range of operating systems such as Windows, UNIX and Mac OS. If you want to create a backup of a CD containing CDFS data onto your hard disk, you can do it just like you would create a backup of any other CD.
