if you don't have any temp file cleaners in your pc , try with your temp directory by typing " %temp% " in run prompt of your source machine..
there's some possibility to have it..
I was trying to be safe. Everytime I saved the document, I would save it on my thumb drive, c drive using save and save as. I can't imagine. When I started to work on the document yesterday, I added more content and then clicked save. It prompted me that I was about to write over the document as I knew it would because I had added new content. I really don't think I did anything different from what I usually do. I can see temp files but when I hover of them, there is not enough content to (kb) to be the document that I loss. Also, it is all scribily, I can't read it.
