Last firmware 3.0 has limitation up to 15000 files.
You can read it at fw's changelog

PS If you have fw 2.0 you were wondering what happens with 12 000 files. So now it is not that bad for you
So, the files are there and can be chosen still, it's just that the memory can only hold 14,996 or whatever?
