In Windows explorer, right click on the file and in the menu options, see if you have the option to "restore from previous versions".

I'm not sure if this option was available in Windows 7, it's available in Windows 8 & 10.

As it was an overwrite (rather than a corruption) the fact it is a PDF makes no difference. Recovering from overwritten files is much more tricky than deleted ones. Try this (free version):

It once helped someone on here with a particularly difficult recovery.

this program is if you lose or delete a file, not if you overwrote a PDF file.

As I said, the fact that it's a PDF file makes no difference whatsoever - it is simply an overwritten file.

Did you try the program, there is still a chance that it will be able to recover it?
If not then what you need is something professional, the sort of thing that the FBI use. This would be highly expensive.

Thank you Derek. The software did not work because all I received was the programing code; which I do not understand. Additionally, it asked which program to use to open the document. I tried several including notebook and still it is programing code. I did review the code for any indication of the file, but was still unsuccessful.

Check out #4.

I think you are just seeing an overwrite of the file in the original place - hence what you call code, which is actually a corruption. What you need is an ambitious program that uncovers and analyses traces or footprints. Loads of money I'm afraid.

"Restore from previous versions" *is* available in Windows 7,
but I don't know exactly how it works. How would it work in
this particular case? How would previous versions be saved,
which program would save them, and how would Windows
know about it?

My wild guess would be that whenever a file is saved with the
same name as an existing file, the old file is kept intact and a
pointer is set to it in "System Volume Information". But that's
just a wild guess.

I knew about the previous versions option but I never really knew how it worked until I read that article, very informative.

I'm going to recommend this option more often now when people say they have overwritten or deleted a file.
