What if you try a different 3rd party file manager, like Total Commander or Solid Explorer? I'm not a fan of ES File Explorer, ever since they started adding lots of useless (and suspicious) junk from DU.
Hey man... Thanks so much for taking the time and helping... But I went to settings and then storage.. I was able to move the video easily... After I moved the video I had to hit refresh on the sd-card for the video to work, but it did.. Thanks again for taking the time...I thought there had to be some simple way to do this, but I had no idea...
LOL, there you go! I find that preinstalled file manager apps tend to be clunky, which is why I like some of the 3rd party ones that were mentioned previously.
