I'm having a problem using the Galaxy Tab S to transfer a video file onto my computer. The settings say it's being used as a storage device when the USB cable is connected to the computer. But with I click on the video file I want to copy onto my computer, and select Copy, then go to paste it into the appropriate file on the computer I get a message "The requested resource is in use". I've managed to transfer a couple of small videos onto the computer, but it chokes on the larger one (about 1GB). I need to be able to download these videos using the tablet, then transfer to the computer.
