Hello, I copied folders that contained mp3 songs into my ( USB mp3 player), the problem is when I'm trying to open the folders using the mp3 players I found the folder empty or error files, I've tried the format or the scanning for viruses and coping the files again and again but it doesn't work .... any help ?
