Is there a file manager on the Ellipses 8? Most android devices have one....
Not natively; you might try:
ES File Explorer File Manager - Android Apps on Google Play
I don't think these file managers can move stuff to the SD card unless the tablet is rooted! Sounds like it's an Android 'feature'. Also, if I were able to move these Google movies, would the Google Movies app find them in the new location?
What I did was change the default save location to the SD card, remove the movies from the device, then re-download them. Seems to have worked.
Still I am getting a 'license not found' error on wifi. I am forced to start the download with wifi turned off, then after it starts turn wifi on. Pretty weird. There is another thread about this somewhere.....
Can you plug the tablet into a PC and manipulate it like a flash drive or like you would with your phone?
