If you wish to play large numbers of files, folders,
playlists or sessions minimize the length of the file,
folder or playlist name. You can also play an MP3 CD
that was recorded using no file folders. The system can
support up to 11 folders in depth, though, keep the
depth of the folders to a minimum in order to keep down
the complexity and confusion in trying to locate a
particular folder during playback.
Root Directory
The root directory will be treated as a folder. If the root
directory has compressed audio files, the directory
will be displayed as ROOT. All files contained directly
under the root directory will be accessed prior to
any root directory folders. However, playlists (Px) will
always be accessed before root folders or files.
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 contains only compressed files, the files
will be located under the root folder. When displaying the
name of the folder the radio will display ROOT.
When the CD 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. When the radio displays the name of the
folder the radio will display ROOT.
Order of Play
Tracks 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.
•
If the CD does not contain any playlists, then play
will begin from the first track under the root
directory. When all tracks from the root directory
have been played, play will continue from files
according to their numerical listing. After playing the
last track from the last folder, play will begin
again at the first track of the first folder or
root directory.
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.
See DISP later in this section. The new track name
will appear on the display.
