saving word files from an email

[Len]

I opened a Word document sent to me via email. I did
some work on the document and then closed the screen in
Word. I was prompted to save the file, which I did. I
wasn't asked where I wanted it saved to. I assumed it
would be saved in the email file I originally opened.
When I reopened the original email, the updated file was
not there - only the original one. I need to know where
this file got saved to.

My thought is that it would get saved in the directory
identified as the location for autorecover files. Its
not there.

Please help. This was a lot of time spent and hopefully
not lost.
