About discs and files
Music files recorded on CD-R/-RW, DVD-R/-RW/+R/+RW and USB memory device are divided into large segments (folders) and small segments (files).
Files are stored in folders, and folders can be placed for storage in a hierarchy. The unit can recognize up to 8 levels of folders.
When writing music files on a DVD-R/-RW/+R/+RW or CD-R/-RW disc, set the writing software’s format to “ISO9660”. The files may not play properly if they are recorded in other formats. For details, refer to the instructions of your writing software.
