You exported what "files" and how?
You are attempting to back up data by changing their file type? That's not
backing up.
If you need to know how to backup OE data, ask in an OE group. This is a
group to support Outlook from the Office group of programs. Outlook Express
is a part of Internet Explorer and is a quite different program despite its
similar name..
You will probably get a faster and more expert answer if you post this to an
outlook express news group.
Try posting in one of these newsgroups:
microsoft.public.windows.inetexplorer.ie5.outlookexpress for OE 5.x
microsoft.public.windows.inetexplorer.ie55.outlookexpress for OE 5.5x
microsoft.public.windows.inetexplorer.ie6_outlookexpress for OE 6.x
A good website for information on OE is:
