in the order they were recorded.
•The maximum allowable number of files in a disc are as follows:
- number of files : 512 (including number of folders)
•The maximum allowable depth of nested folders is 8.
•It may take 30 seconds or more before the unit can start play
of MP3 files, depending on the number of recorded files and
