Microsoft Document Imaging (MDI) just Discovered

I am brand new to the built-in XP Microsoft Docuemnt Imaging tool.

It is my understanding now that a multiple sheet FAX (tif) or several
scanned document may be manipulated by the XP MDI tool. Until now, I
have been scanning individual sheet documents and saving as jpeg files
with page 1, page 2, etc.

With MDI, will I be able to merge additionally scanned in document
sheets into an existing MDI file ? For example, I try to keep a
running file on one of the several medical clinics that I visit. Once
I have scanned in several sheets and closed the first MDI file, will
I be able to append additional informational sheets into that existing
MDI file ?

Also, are the files created with use of MDI readable from other image
viewers, such as IrfanView: will either application be able to pull in
and display their inddependantly produced TIF files ?

Also, is is possible to get a TIF image that is saved on disc into a
MDI (empty) window, e.i., without scanning the original paper
document?


Thanks.
