• Make sure playlists have a .mp3 or .wpl extension (other file extensions might not work). Root Directory The root directory of the CD-R or CD-RW 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. • 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. 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. • Finalize the audio disc before you burn it. Trying to add music to an existing disc can cause the disc not to function in the player. Playlists can be changed by using the S c and c T folder buttons, the a knob, or the SEEK arrows. An MP3/WMA CD-R or CD-RW that was recorded using no file folders can also be played. If a CD-R or CD-RW contains more than the maximum of 50 folders, 50 playlists, and 255 files, the player lets you access and navigate up to the maximum, but all items over the maximum cannot be accessed. 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 display 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 goes to the root folder. When the radio displays the name of the folder the radio displays ROOT. 4-103
