Micro SD card videos disappeared?

I moved videos from the internal memory of the mobile phone to a micro sd. Unfortunately nothing is displayed neither on the mobile phone, PC, laptop, etc. The properties are 2.5 Gb but when I open the card nothing is to be found except a few other small files that have nothing to do with the videos.

I've already tried everything possible but can't get any further!

Do you know google drive? This is a "digital storage place for files", there you can upload files and retrieve them on another device, very reliable and free, no advertising… Lol.
