Depends on how you attached the file, but the default behavior is duplicate
to what is stored on file system.

In OL2003 if emails in my Sent Items have attachments are the attachments
in
this folder a duplicate of the file or is it only a link?

I have many emails in my sent items folder which have attachments of 5MB
and
don't think its good to unnecessarily expand the Outlook database.
