CD‐R‐ or CD‐RW‐Supported File
and Folder Structure
The radio supports:
. Up to 50 folders.
. Up to 8 folders in depth.
. Up to 50 playlists.
. Up to 255 files.
. Playlists with an .m3u
or .wpl extension.
. Files with an .mp3, .wma,
or .cda file extension.
Root Directory
The root directory is treated as a
folder. Files are stored in the root
directory when the disc or storage
device does not contain folders.
Files accessed from the root
directory of a CD display as
F1 ROOT.
Empty Folder
Folders that do not contain files are
skipped, and the player advances to
the next folder that contains files.
Order of Play
Compressed audio files are
accessed in the following order:
. Playlists (Px).
. Files stored in the root directory.
. Files stored in folders in the root
directory.
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.
. 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.
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 4 pages are
shortened. The display does not
show parts of words on the last
page of text and the extension of
the file name is not displayed.
Preprogrammed Playlists
CDs that have preprogrammed
playlists reated using WinAmp™,
MusicMatch™, or Real Jukebox™
software can be accessed; however,
there is no playlist‐editing capability
using the radio. These playlists are
treated as special folders containing
compressed audio song files.
