Directories and playback order of MP
files
The album and track (MP3 files) directories
on a data CD have the structure shown in the
following figure below, with a playback order of
            .
If an album contains a sub-album, the tracks in
the sub-album have higher playback priority (for
example, if album  is contained within album ,
then track  in album  will be played before the
other tracks, such as track  or ).
Albums are shown in the list display of the unit in
order of           . Album
icons that do not contain any tracks directly below
them (such as  in the figure) do not appear in the
display.
