How are MP3 files recorded
and played back?

”
—in PC terminology.
During recording, the files and folders can be
arranged in a way similar to arranging files and
folders of computer data.
“
Root
” is similar to the root of a tree. Every file
and folder can be linked to and be accessed from
the root.

MP3 files are recorded on a CD-R or CD-RW,
how they are played back, and how they are
searched for on this unit.

files. However, if non-MP3 files are recorded
together with MP3 files, this unit will take a longer
time to scan the disc. It may also cause the unit to
malfunction.
• This unit cannot read or play an MP3 file without
the extension code <.mp3>.
