I couldn't find it either when I went back to look.
I did a search for .jpg on the C drive in the File Explorer. I showed all the pictures I know I have plus the 2800 that started with AA and BB with some alphanumerical gibberish following.
Then to find it again, I made a shortcut to the desktop, so I could 'open in folder'
So far, nothing is telling me it can't find a photo and I doubt anything will. And in time I'll empty the recycle bin.
