I have been trying to take video files that I have downloaded on my laptop & move them to my sd card (16g class 10) so I can watch them on long trips & I have yet to figure out where the files are on my phone or even how to play them. I created folders for music & videos & filled them up. I can access the music files through the stock player & poweramp but I'm striking out with the films. If you can't tell I'm new to all this & the triumph is my first android which i've owned for 3 months. not the flashiest but its an upgrade from a cheap bb curve. PLEASE HELP!!!!!!!
