I cannot move videos from my iPhone 7 Plus (IOS 11.4.1) to my Win 10 Pro 64 bit desktop. I opened the folders in my iPhone and searched for the .mov files. Then I highlighted the ones I wanted and did a cut/paste to the desktop. 37 files out of 150 did move. The remaining ones will not move and I get a device is unreachable error. I can see the videos on my phone. Also, in explorer, there are only blank icons, no thumbnails showing up for these files. The other thing that I do not understand is that in explorer, all the other folders are showing up as empty when I know they are full of photos and videos.
