MP3 playing order
When selected for play, Track Search, or for Folder Search, files and
folders are accessed in the order in which they were written by the CD
writer.
Because of this, the order in which they are expected to be played may
not match the order in which they are actually played. You may be able
to set the order in which MP3 are to be played by writing them onto a
medium such as a CD-R with their file names beginning with play
sequence numbers such as "01" to "99", depending on your CD writer.
For example, a medium with the following folder/ file hierarchy is
subject to Track Search, or Folder Search as shown below.
