NOTES
This unit assigns folder
number. The user can not
assign folder numbers.
MP3/WMA/AAC files in the
USB portable audio player/
USB memory are played
in the same order as they
were copied to the USB
portable audio player/USB
memory.
To specify the order in
which files in the USB
portable audio player/USB
memory are played, we
recommend the following
method.
1 Using a personal computer,
add a number indicating
the playback order in
front of the file name, e.g.
[001xxx.mp3] or [099yyy.
wma].
2 Put the files into a folder.
3 Copy the folder to the USB
portable audio player/USB
memory.
Depending on the computer
environment, it may not
be possible to specify the
order by this method.

It is not possible to check
folders that do not include
MP3/WMA/AAC files.
(These folders will be
skipped without displaying
the folder number.)
MP3/WMA/AAC files in
up to 8 tiers of folders can
be played back. However,
there is a delay in the
start of playback on discs
and USB portable audio
player/USB memory with
numerous tiers. For this
reason we recommend
creating discs with no more
than 2 tiers.
It is possible to play back
up to 192 folders on one
disc.
It is possible to play back
up to 255 folders on one
USB portable audio player/
USB memory.
