VCD/SVCD/CD
A VCD/SVCD/CD consists of “tracks”.
In general, each track has its own track number. (On some discs, each track may also be further divided by indexes.)
Track 1 Track 2 Track 3 Track 4 Track 5
MP3/WMA/WAV/JPEG/ASF/DivX/MPEG1/ MPEG2 files
Audio, still pictures and video are recorded as tracks/files on a disc or a USB mass storage class device. Tracks/files are usually grouped into a folder. Folders can also include other folders, creating hierarchical folder layers.
This system simplifies the hierarchical construction of files and manages folders by “groups”.

Up to 150 files
This system can recognize up to 4 000 tracks/files on a disc. Also, the system can recognize up to 150 tracks/files per group and up to 99 groups on a disc. Since the system ignores the tracks/files with numbers exceeding 150 and the groups with numbers exceeding 99, these cannot be played back. If there are any type of files other than MP3/WMA/ WAV/JPEG/ASF/DivX/MPEG1/MPEG2 files on a disc, those files are also counted in the total number of files.
