Root Directory
The root directory is treated as a folder. If the root
directory has compressed audio files, the directory is
displayed as ROOT. All files contained directly under the
root directory are accessed prior to any other directory.
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.
No Folder
When a CD contains only compressed files, the files are
located under the root folder. The next and previous
folder function does not function on a CD that was
recorded without folders or playlists. When displaying
the name of the folder the radio displays ROOT.
When a CD contains only compressed audio files, but
no folders, all files are located under 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:
•
Playback begins from the first track under the root
directory.
•
When all tracks from the root directory have played,
playback continues from files, according to their
numerical listing.
•
After playing the last track from the last folder, the
player begins playing again at the first track of the
first folder or root directory.
File System and Naming
The song name in the ID3 tag is displayed. If the song
name is not present in the ID3 tag, then the radio
displays the file name without the extension (such as
MP3/WMA) instead.
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.
