Lost a folder with lots of file when installed a new OS, forgot to back up the folder. How to retrieve it back?

I was having Windows vista earlier and apparently it was running very slow and I purchased new Windows 7 professional and formatted the C drive and loaded the new OS, I copied most of the files but forgot to back up a folder in C drive which had major work related files.

Now I want that folder back with most of the files.


Solution 1:

Sorry, it's gone. If you formatted the drive and did a whole OS install, the chances for recovery are extremely thin. There has been a lot of stuff written to the disk. No, I'd say the chances are almost zero. Sorry.
