MP3 [JPEG] discs
On an MP3 [JPEG] disc, each still picture (material) is recorded as a track [file]. Tracks [Files] are usually grouped into a folder. Folders can also include other folders, creating hierarchical folder layers.
This unit simplifies the hierarchical construction of a disc and manages folders by “groups”.

This product can recognize up to 1000 tracks [files] in a disc. Also, the product can recognize up to 150 tracks [files] per group and up to 99 groups in a disc. Since the unit ignores the tracks [files] whose numbers are exceeding 150 and the groups whose numbers are exceeding 99, they cannot be played back.
•If there is any type of files other than MP3 [JPEG] files in a folder, those files are also counted in the total file number.
