I cut and pasted many images from my Sony Xperia XZs (G8231) to my laptop running Win 10. I recall being able to open and view them on my computer at the time, but after checking now, only a few pictures and the videos will open. the rest now all say that they are 3.40 GB on large and exactly 4.00 KB on the disk neither of which sounds right at all. Firstly, I'd like to be able to restore them, if possible, if not, how do I prevent this from happening in the future? Thank you in advance for your help.
