Empty Directory or Folder
If a root directory or a folder exists somewhere in
the file structure that contains only folders/
subfolders and no compressed files directly
beneath them, the player advances to the next
folder in the file structure that contains compressed
audio files. The empty folder does not display.
No Folder
When the CD contains only compressed files, the
files are located under the root folder. The next
and previous folder functions do not function on a
CD that was recorded without folders or playlists.
When displaying the name of the folder the
radio displays ROOT.
When the CD contains only playlists and
compressed audio files, but no folders, all files
are located under the root folder. The folder down
and the folder up buttons search playlists (Px)
first and then goes to the root folder. When
the radio displays the name of the folder the
radio displays ROOT.
Order of Play
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.
•
If the CD does not contain any playlists, then
play begins from the first track under the
root directory. When all tracks from the root
directory have played, play continues from
files according to their numerical listing.
After playing the last track from the last folder,
play begins again at the first track of the
first folder or root directory.
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. See DISPL later in this section for
more information. The new track name displays.
