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.
Tracks are played in the following
order:
. Play begins from the first track in
the first playlist and continues
sequentially through all tracks in
each playlist. When the last
track of the last playlist has
played, play continues from the
first track of the first playlist.
. Play begins from the first track in
the first folder and continues
sequentially through all tracks in
each folder. When the last track
of the last folder has played,
play continues from the first
track of the first folder.
When play enters a new folder, the
display does not automatically show
the new folder name unless the
folder mode has been chosen as
the default display. The new track
name displays.
