[sajjad_pge]

i am using Xperia SL. In my internal storage there is a folder named "my music" which contains 362 songs, but when i connect my phone with & open that "my music" folder, it shows that there are only 36 songs shows in my pc. Similarly some folder also not showing in my pc when i connect my phone via cable.what can i do now?
