8 char filenames and paths won't play

This may be related to the board I'm using, I have the "koobook module . The chip on it is the DY1703A.

I have files in folders, everything works great except I cannot play a sound which has a folder which is 8 characters, or the filename (excluding .Ext) which is 8 characters. Took a bit to figure out why some of my sounds were skipped over, but I narrowed it down to that.

I checked the command bytes which were being sent and they appear correct, so I'm wondering if 8 char filenames/folders were tested or if this might just be a limitation of my board? Not a big deal on my end but it sure took some figuring out.

IIRC names can be only 5 characters, excluding the extension. Are you saying it only worked with 4, or that 6 didn't work? Because the latter is expected.
