• Avoid subfolders. The system can support up to 8 subfolders deep, however, keep the total number of folders to a minimum in order to reduce the complexity and confusion in trying to locate a particular folder during playback. • Make sure playlists have a .m3u or .wpl extension (other file extensions may 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. • 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. Change playlists by using the previous and next folder buttons, the tuner knob, or the seek buttons. An MP3 CD-R that was recorded using no file folders can also be played. If a CD-R 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. Root Directory The root directory of the CD-R 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 is not numbered or displayed. 234
