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
: Folder
: Compressed audio file
Level 1
! 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 character code order.
! 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.).
