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.

Playlists that have an .m3u or .pls file extension and are stored on a USB device may be supported by the radio with a USB port.

Playlists can be changed by using the softkeys below the and tabs, the knob, the SEEK button, or the SEEK button. An MP3 CD-R or CD-RW that has been recorded without using file folders can be played. If a CD-R or CD-RW contains more than the maximum of 50 folders, 15 playlists, and 512 folders and files, the player allows access and navigates up to the maximum, but all items over the maximum are not accessible.
