Some time ago I copied an MP3 file onto my Sh*t6, presumably to the 'Music' folder. Maybe not. Maybe I copied a music file to some other folder? Thing is, I need to replace it on my PC - and now I cannot find the darn thing on my phone? The track is there, I can play it on my phone, but I don't know where the phone is hiding it? This is an MP3 file I paid for online, nothing to do with Android or Samsung, added to my phone, but now it seems hidden? Why, how and how do I get it back? Asking my PC to search my phone results in nothing, even though I can play the damn track and it's obviously there.
