Why cant I move music to my sd card?

[LegInsomniak]

So about a week ago my phone started doing this. I download music onto my phone (don't have a computer to use) and I prefer to have my music all on my 16GBs micro SD card. But every time I try to move the music to my SD card it deletes all the files in the folder. I don't know why it does this I've been doing this for a while and moved 5GBs of music already so I have no idea. I have Android 4.4 KitKat. (No pc)

Welcome to Android Central! Where are you downloading the music from? It's possible the SD card is corrupt or failing--have you tried a different card?
