Lost 2,000 Word Essay. Please help me find it!

Ok, so let's start off by saying I've tried doing extensive searches on my harddrive with 5 different programs, but they can't seem to find the "exact" file name. Anyways, so here it goes:

I downloaded a .doc file with firefox (my half done report from one computer to another) I said "open" which put it into the Temp folder (C:\Doc & Settings\User\Application Data\Temp) Soo, there's my mistake. I began editting the paper, thinking I had put it somewhere else. I kept hitting control S to save, not really thinking about where I had the document. After I was done I closed it.. Now, today when I went to go find it, I couldn't find it anywhere. I did searches as well as data recovery attempts to try and find it. Do u know if there's something I haven't tried that is going to be a sure way to get it back? Otherwise I'm going to be writing quite a bit tomorrow. Please help if you can!

Thanks in advance,
Alucard

Jam it back in, in the dark.

Appreciate all the comments, the document was not opened overnight, and from what it seems the document simply disappeared. Using file recovery programs, even doing the deep scans it doesn't even find the original document. Since the paper is due tomorrow I think I'm going to suck it up and just re-write it. Thanks for the attempts though guys

There's nowhere I can't reach.
