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.
