When pruning unnecessary duplicate photos, I somehow accidentally deleted a whole series of pictures.
Can I restore the deleted photos (like that), on /e/ and, if so, how?
Is it possible to restore deleted photos on /e/ either through the cloud or on device, via something like the Trash bin?
Have you searched the web? There are several tools available
