I tried using recuva to get some deleted photos and while most were unsalvagable there were a few that were marked as ‘excellent’ condition. I couldn’t preview them in recuva and when I downloaded them they wouldnt open either. I tried Stellar photo repair and that didnt work, I also tried viewing them in irfanview but it just said incorrect file format. Are these at all salvageable?
