A friend emailed me a couple of pdfs by attachment. I downloaded them and saved them, and opened them with Quickoffice. However, I cannot find them. They are not in the downloads folder, and when I open Quickoffice they do not appear in the Recent Files. The only way to find them is to go back to the original email. Where would they be stored? (One reason that I'd like to know is so that I can delete them: at the moment the only way seems to be to delete the email, which I don't want to do).
