[198232]

I have the lg g stylo 8 gb with 16 gb sd card and I use tubemate to dl my music.Tube mate wouldblnt DL the music directly to the sd card so I moved them manually. Well I went to settings/general/storage and usb... Well the files are on the internal as well as the sd card it wont let me delete them. I get a message that says some files could not be deleted and it deletes nothing at all. It just makes no since having a sd card if I cant even save my music on it and keep my 2gb of space I have left open... Please help i am so frustrated.

Welcome to the forums! Have you tried moving the files with the phone connected to your PC? Sometimes that can complete actions that the phone can't.
