Whether you have deleted a file or folder by mistake or lost them in a system crash, it's natural to want that data back. Digital photos of friends and family can be irreplaceable, and losing a document that's school or work related can set you back days or weeks.
The good news is, the files are probably still on your hard drive. Even when you empty the recylce bin, Windows doesn't actually delete the files themselves, but simply marks that area of the hard drive with a notation that it can be overwritten in the future.
So the first thing you need to know is to do as little computing as possible since every time you create a new file (even those temporary internet files), you run the risk of writing over the deleted data by mistake.
There are several programs you can use to attempt to recover the data yourself (Recuva for example). The problem is, when you install those programs you again run the risk of overwriting the data you're trying to recover. If you're going to try anyway, I recommend installing the program to an external hard drive or USB drive.
Or you can email me to attempt the recovery for you.
