I need help. I had some video files on a large external hard drive that I deleted folder by folder. I have never used that hard drive since I deleted these folders. I was able to recover all of the data but none of the videos or pictures will play or display. I don't understand since I did not add any new data after I deleted everything. How do I fix the files I recovered? I have tried to use some video repair tools and none of them seem to work.
