Additional Information
! Compressed audio files in up to 8 tiers of
folders can be played back. However, there is
a delay in the start of playback on discs with
numerous tiers. For this reason we recom-
mend creating discs with no more than 2
tiers.
! It is possible to play back up to 99 folders on
one disc.
