"I was trying to move my pictures from my Galaxy S25 to a USB stick through my PC using Windows File Explorer. The 'Camera' folder on the phone was renamed in error, and I did a 'folder rename undo' not realizing what had happened. Now all my pics in that folder are gone!!! 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?"

Generally, you can quickly retrieve the deleted files on Galaxy S25 from the backup file if there is one already.
