•
Minimize the length of the file, folder or playlist
names. Long file, folder, or playlist names, or a
combination of a large number of files and
folders, or playlists may cause the player to be
unable to play up to the maximum number of
files, folders, playlists, or sessions. If you wish
to play a large number of files, folders, playlists,
or sessions, minimize the length of the file,
folder or playlist name. Long names also take
up more space on the display, potentially
getting cut off.
•
Finalize the audio disc before you burn it.
Trying to add music to an existing disc may
cause the disc not to function in the player.
Root Directory
The root directory of the CD-R is treated as a
folder. If the root directory has compressed audio
files, the directory will be displayed as F1
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-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 displaying the name of
the folder the radio will display ROOT.
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. When the radio displays the name of the
folder the radio will display ROOT.
