How many files can be stored in a USB flash drive to play back music in it?
Up to 30,000 tracks can be stored.
NOTE: For CMT-SBT20 and CMT-SBT20B, up to 999 tracks can be stored.
However, when an excessive number of files other than music tracks are stored, or when the folder structure is complicated, it may take a long time to read files causing the playback to be unable to start.
