Notes
! This product assigns folder numbers. The user
can not assign folder numbers.
! If you are using a folder that does not contain
an MP3 file, the folder itself will display but
you will not be able to see any files in the
folder.
! MP3 files in up to 8 tiers of folders can be
played back. However, there is a delay when
starting playback on discs with numerous
tiers. For this reason we recommend creating
discs with no more than 2 tiers.
! It is possible to play back up to 253 folders on
one disc.
