I can move all music and pix on my LG tablets internal storage to the SD card, but not any mp4 Videos! Nowhere is there the option to MOVE! These are precious recent family wedding videos I need to preserve, besides they are using up almost all remaining internal storage! I have already moved and deleted all I can. I have a 32Gb SD card with 23GB available. My tablets internal storage is down to 164MB and it's barely functioning!
