The radio can play discs that

which they were recorded to
the disc.

Root Directory
The root directory of the disc is
treated as a folder. If the root
directory has compressed audio
files, the directory displays on the
radio as the CD label.
If a disc contains both
uncompressed CD audio and
MP3/WMA files, a folder under the
root directory called CD accesses
all of the CD audio tracks on
the disc.
Empty Folder
Folders that do not contain files are
skipped, and the player advances to
the next folder that contains files.
Order of Play
Compressed audio files are
accessed in the following order:
Playlists (Px).
Files stored in the root directory.
Files stored in folders in the root
directory.
