Sequence of playing MP3 files

For some writing software, input "01" ~ "99", for example, before the file names in the sequence of playing and then record into a CD-R, etc, sometimes you may setup the sequence of playing.

Writing files onto a medium

When a medium containing MP3 data is loaded, the unit checks all the files on the medium. If the medium contains a lot of folders or non-MP3 file, therefore, it takes a long time until the unit starts playing MP3 file. In addition, it may take time for the unit to move to the next MP3 file or a file search or folder search may not be performed smoothly. You should not write non-MP3 file or unneeded folders along with MP3 file on the medium.
