Yesterday my computer was reformatted *I'd prefer not to explain why

* I've used Piriform's Recuva to uncover almost about 60 gigs of the files that were lost. However, I'm unable to open any of the files.
The files (ranging from word documents, excel files, image files, videos, etc) are in a folder, and are acknowledge as taking up space in my hard drive. They even have the previous modified times and so forth.
When I attempt to open up any file, the file does not open, even on a different computer. For example, when I open image files, an image comes up with a red "X" and it says that it's not the proper format.
I don't know what to do. I'm mostly concerned with all the pictures that were lost.
I'm currently running Windows XP with Service Pack 3.
