Hi! My videos have turned into images!? What now? LG V20 ,Thank you in advance hope you can help!

[Android Central Question]

I maxed out of storage memory in my internal storage and SD card. I plugged my phone into computer and transferred some files and then wanted more free space on my internal storage so I moved some things from internal storage to SD. This file of 795 videos was in my internal storage and I think it was always there. It's still there but no longer videos!

This happened a while after I had already disconnected from the computer.

You're looking at thumbnails of videos on your phone - but the videos aren't there any more. Restart the phone and the thumbnails should disappear. Or copy the videos back to the phone.
