Audio File Playback Order
When playing audio files stored within multiple folders, the playback order of each folder is automatically set when
the unit reads the media. The files in each folder will play in the same order in which they were added to the media.
(This order may appear differently on your computer and/or in your software than it does on the unit.)
The folder structure also determines the playback order:
o
For audio files on a CD-R,
files in
all
folders on the
first
level will play, then files in
all
folders on the
second
level,
then on the
third
level, and so on.
o
For audio files on a USB device,
files in the
first
folder on the
first
level will play, then files on the
second
level in
that same folder, then files on the
third
level in that same folder, and so on. After playing all files on all levels of
that first folder, the same process will continue for files in the
second
folder on the
first
level.
