Recovering pictures from Galaxy S6 after folder rename "undo" in Windows File Explorer

A

AC Question

I was trying to move my pictures from my Galaxy S6 to a USB stick thru my PC (USB connected) using Windows File Explorer. The "Camera" folder on the phone was renamed in error (thanks, kitten on keyboard), and I did a 'folder rename undo' not realizing what had happened. Now all my pics in that folder are gone !!!

I have found some of the pics using ES File Explorer, and have searched for the folder, but I think it was deleted by File Explorer. It is NOT on the PC either.

I assume the pics are still on the internal memory somewhere but hidden.

Any suggestions ? Even trusted software to use ?

Thanks.
