Hi Macropod,

Thank you for answering. The reason I differentiated between Word 2007 and 2010 is that I could not find the described places to click on when I googled for help. Maybe they're there but I overlooked them.

I went to the link you provided. I tried inserting a file into a blank document and I tried starting Word with the /a switch. I still got the error message with both methods. The site said to only use the third option--deleting the Word registry subkey--if the problem did not occur using the /a switch. So I didn't do it. I'm not sure what I'm looking for here.

Where would I access Word Options, Resource, Diagnose please?

I am not trying to access files on removable media, but from my C drive. For what it's worth, I back up files on a slave hard drive and get the same error message when trying to access the same files there.

You mention a temp folder. Is this for Word alone? Or is it found elsewhere? I can't seem to find it in Word.

Thank you for your help.
