I have a ROOTED Samsung Galaxy Tab Pro 8.4, (SM-T320) running KitKat 4.4 with16 GB, and a 64 GB ext sd card. I have TBU on it but am not familiar with how to use it. I wish to back up and move some apps to the ext sd card as well as just move some files onto the ext sd card. When I run TBU the back ups end up on the internal sd. How do I get them to ext sd to free up memory? Can TBU be used to also move other files onto the ext sd card or do I need to do that with an app like ES File Explorer. If so, how do I do that. Sorry I'm so ignorant but I'm afraid to mess around and screw things up. Thanks in advance for the assistance.
