How do I... Archive Outlook e-mail without a PST file?

When employing the folder system to archive Outlook e-mail without a PST file, there's one item you need to watch. When you copy an e-mail message from Outlook to another folder on your hard drive, Windows creates the file using the message's Subject Line as the filename (adding the .MSG file extension). If you copy multiple e-mail messages at once that possess the same Subject Line, Windows simply appends numerals within parentheses to the end of the identical filenames, thereby creating unique filenames for each e-mail message. It works great.

If, however, you later add an e-mail message to a Windows folder that already holds an e-mail message possessing an identical Subject Line, Windows will present the Confirm File Replace dialog box.
