[Q] Data loss from internal storage and sd card

Hi guys

I plugged my note into my pc using usb cable to transfer games I had downloaded. After unplugging I discovered that all video files and all picture files have disappeared from both the internal sd and my sd card. This is really confusing. I've no idea how this has happened and what I can do to restore it all. This is really upsetting as we had a new baby recently and all my photos of her and my other kids have disappeared. :crying:

Any advice will be gratefully received.

Many thanks in advance.
