Can Phoenix perform a File level backup of the Windows drives A:\ and B:\?

A:\ and B:\ drives (or drive letters) are usually reserved for floppy disk drives. If the device does not have a floppy disk drive, the drive letters A and B can be assigned to volumes.

Phoenix agent checks whether a drive is fixed or removable and ignores all the removable drives. Since A:\ and B:\ are removable drives by default, Phoenix ignores their backup.
