“It was my daughter’s first birthday, and we clicked a hell lot of images just to keep that day alive in our lives forever. But suddenly, one day, when I was showing those images to my bestie, some of the images were totally destroyed. There were some colourful patches in the place of our images. My friend told me that it is happening because of the corruption in the images. I don’t know how it happened, why my images are corrupt, and how to fix it. I don’t even know if they can be fixed or not. It is CR3 file format images clicked from my Canon camera. Can anyone please help know if my files are recoverable?
