I'm running Vista with Office 2008 and Microsoft Mail. I opened an e-mail
attachment that was an Excell file and made changes to it and
inadvertently
hit 'Save' instead of 'Save as' when I closed Excell I got no warning but
now
I can not find the file. I tried searching the entire drive. Does anyone
know
where the file might be located?

If you click the large button icon at the top and select Open, and click the
Recently Changed link, does the file show up in the list that appears?
