If none of the programs worked, and the programs actually did a deep drive scan (which takes probably hours), then you can't do anything. A file-recovery is successful, when you do it right after you deleted (including replacing) the file. If you wait too long (which you probably did), then the drive uses the sectors again and overwrites the data.
You can employ a professional company to try to recover your data. I have heard things about magnetic properties of disks that allow you to recover data after it is written over (not numerous times) but you are in the forensic territory there, sorry to say.
That is actually possible, but will cost you probably a few 1000$ per Gigabyte and you don't even know, if they recovery anything useful.
I'm sorry to say than, but your files are probably lost.
