I actually missed the part where he said that. Embarrassing indeed. Aside from the windows.old folder there isn't another practical way I can think of to retrieve his old files.
It can happen to anyone, it's nothing to worry about too much - although we've both given similar advice, it doesn't seem to help the OP because that option doesn't really exist in his case.
dovjann, your only option is to try a professional data rescue service, and they will tell you how likely the data recovery is in a particular case. Of course, it all depends on how much value is in your crypto wallet - and how much the possible rescue service would cost.
Lucius thanks for your advice, but none of the companies will help me in my case, they will use the same tools/softwares I used, it's SSD, you can't do much with it, if it would be HDD then yes, there are laboratories for it.. I overwrite the data already by using laptop 3-4 weeks unfortunately. Well you learn from your mistakes, it is as it is, I tried everything and I appreciate for your help too!
