Root Directory
The root directory of the CD-R or CD-RW disc is treated
as a folder. If the root directory has compressed audio
files, the directory is displayed as F1 ROOT. All files
contained directly under the root directory are accessed
prior to any root directory folders. However, playlists (Px)
are always 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
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-R or CD-RW disc contains only
compressed files, the files are located under the
root folder. The next and previous folder function
does not function on a CD-R or CD-RW that was
recorded without folders or playlists. When displaying
the name of the folder the radio displays ROOT.
3-102
When the CD-R or CD-RW disc 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 recorded to the CD-R or CD-RW disc 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 you
have chosen the folder mode as the default display.
The new track name displays.
