How Do I Recover A Windows Hidden Folder After A Reinstall

Around 15-20 days back I opened that folder lock. Then for some reason I installed Windows 7 and also Windows 8. When I did all these things, I found that my locked, hidden folder not available on my drive.

I tried so many software to recover that file, but no matter what I try, I can’t recover that file.

I already recovered these locked folders earlier, also when it was deleted. But this time I am not able recover that. I am not sure that folder was deleted by antivirus or due to formatting.

I need your help. Please, that file is very important for me.

Thanks, I’m waiting for reply.
