hello

I was given this mp3/mp4 player(from china0) by my fren as a give.
Iniatialy it works fine but now i have this problem.
The problem is that when i open up the root directories and choose the folder
(I have 5 or more folders of group songs) that i wanted to play and open up the folder,
it never shows the mp3 files in that folder.So it keep playing the first folder of mp3 in the root directories.
But when i hook up with my pc, the mp3 files is still there ( all of them)
Plzz anyone who knows how to solve this problem and help me plzzzzz

That's how the firmware is made.

Go to your folder and long-press Mode (but shorter than how you press it to access the main menu) Now it'll load the mp3s from that folder.
