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 is 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.
