Pioneer CD-UB100 - Manual (Page 18)

! Up to 500 folders on a USB portable audio
player/USB memory can be played back.
! There may be a slight delay when starting
playback of audio files on a USB portable
audio player/USB memory with numerous
folder hierarchies.
! File extensions such as .wma, .mp3 or .m4a
must be used properly.
! Only 64 characters from the beginning can
be displayed as a file name (including the
extension such as .wma, .mp3 or .m4a) or a
folder name.
Depending on the character sets, only the
first 32 characters may be displayed.
! The text information of some audio files
may not be correctly displayed.
! There may be a slight delay when starting
playback of audio files encoded with image
data.
The sequence of audio files on
USB memory
For USB portable audio players, the sequence is
different from that of USB memory and de-
pends on the player.
Example of a hierarchy

Level 1 Level 2 Level 3 Level 4
! 01 to 05 represent assigned folder num-
bers.
1 to 6 represent the playback se-
quence. The user cannot assign folder
numbers and specify the playback se-
quence with this unit.
! The sequence of audio files/folders to be
played back, selected by the scan play and
displayed in the file name list is determined
as follows:
— The sequence of files is given priority
over the sequence of subfolders.
— In a folder, the sequence of audio files/
subfolders is the same as the order you
copy from a personal computer to the
USB memory.
However, the sequence may be altered de-
pending on the settings and the operating
system of the personal computer.
Also, when you select several folders/files
at one time and copy to the USB memory,
the expected sequence of audio files to be
played back, selected and displayed may
not coincide with the actual sequence.
! If you want to specify the sequence of the
audio files, refer to Example of a hierarchy
on this page and copy the folders/files in
order.
— We recommend that you specify the file
names in the desired playback se-
quence (e.g., 001xxxxx.mp3 for the first,
099yyyyy.wma for 99th, etc.).
