Make sure playlists have a .mp3 or .wpl extension
(other file extensions might not work).
•
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 can 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.

Root Directory
The root directory of the CD is treated as a folder. If the
root directory has compressed audio files, the directory
displays 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 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
searches playlists (Px) first and then goes to the root
folder. When the radio displays the name of the folder
the radio displays ROOT.
