No Folder
When the CD contains only compressed files, the files
are located under the root folder. The next and previous
folder functions have no 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
search playlists (Px) first and then go to the root folder.
When the radio displays the name of the folder, the
radio displays ROOT.
Order of Play
Tracks 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.
•
If the CD does not contain any playlists, then play
begins from the first track under the root directory.
When all tracks from the root directory have played,
play continues from files according to their numerical
listing. After playing the last track from the last folder,
play begins again at the first track of the first folder or
root directory.
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.
See DISPL (display) later in this section for more
information. The new track name displays.
File System and Naming
The song name that displays is the song name that is
contained in the ID3 tag. If the song name is not present
in the ID3 tag, then the radio displays the file name
without the extension (such as .mp3) as the track name.
Track names longer than 32 characters or four pages
are shortened. Parts of words on the last page of
text and the extension of the filename does not display.
Preprogrammed Playlists
Preprogrammed playlists which were created by
WinAmp™, MusicMatch™, or Real Jukebox™ software
can be accessed, however, they cannot be edited.
These playlists are treated as special folders containing
compressed audio song files.
