Hi, thank you for your help.
RichC46 - I don't think i really understand your first suggestion

I only opened the attachment for the first time today so if i went back to a date before then i don't think it would exist at all...would it?
Zigzag - I have tried searching the index for the title or a phrase but it does not return any results. How can i check if it is set to index the entire the drive? Will it have definitely have saved it
somewhere if I was just saving a temporary file?
And finally, dnorris - I located the temporary internet files folder but i cannot see my file there - what would it look like?!
Apologies for all the extra questions - i have just been told by somebody that Word cleans up temporary copies when you save a document and it thinks it has saved a document even when that is technically to nowhere. This is a very pessimistic option and i'm hoping there's a more positive version out there...
Thanks again for your help
