Missing files from internal storage!

[Android Central Question]

I have a folder with pictures of my daughter and family photos and videos and within that folder i have a few more folder with a few other photos and videos. Thing is they've all just disappeared. The folders are all there with their proper names but they're completely empty.. I'm using ES File manager and i have been for a few years now. I've checked my recycle bin and nothing except previously deleted files are there. Where have theu gone? I unfortunately do not have a backup of all these pictures and videos, i now know i should but I really need help retrieving these!
