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 will advance to the next
folder in the file structure that contains compressed
audio files and the empty folder will not be
displayed or numbered.
No Folder
When the CD-R contains only compressed files,
the files will be located under the root folder.
The next and previous folder functions will not be
displayed on a CD-R that was recorded without
folders or playlists.
When the CD-R contains only playlists and
compressed audio files, but no folders, all files
will be located under the root folder. The
folder down and the folder up buttons will search
playlists (Px) first and then go to the root
folder.

Order of Play
Tracks recorded to the CD-R will be played in the
following order:
•
Play will begin from the first track in the first
playlist and will continue sequentially through
all tracks in each playlist. When the last
track of the last playlist has been played, play
will continue from the first track of the first
playlist.
•
Play will begin from the first track in the first
folder and will continue sequentially through
all tracks in each folder. When the last track
of the last folder has been played, play
will continue from the first track of the first
folder.
When play enters a new folder, the display will not
automatically show the new folder name unless
you have chosen the folder mode as the
default display. The new track name will appear
on the display.
