read mail files

Because of an earlier problem--that I think I solved--I have saved some emails in a separate folder which is not part of KMail. However, they are in a format with all sorts of header info, etc. Is there a way to read the files with KMail, while still leaving them in the present folder, that is, copy them to a temporary location that KMail know about and can access, or perhaps make a link from KMail to the directory they're stored in? I really don't know anything about linking files to programs, or vice versa, so if that's the answer, HELP, please. (Don't know if I'm making myself clear. If not, I'll try again.)
