Hi David, even using PDF, my PDF file can be copied by anyone from the
CD.
>convert your PowerPoint to video
>Watermark each slide of presentation & convert it to video format
Both these approach also have the same problem of getting file
copied.
May be I was unclear in explaining the real problem before.
What I want is that user should always require CD in the drive for
seeing the contents. I want that my original file(may be it in any
file format) can not be copied on the system and be viewable from
without CD. Even though it can be copied but then it should become
useless for the user to see the contents from his machine without CD.
Is there some way I can make it CD dependable?
Thanks again!

A far as I know, you're asking for the impossible. Even if you could restrict a
normal file copy of the contents, there's always a way make an ISO image of the
CD media that will bypass all protection methods.
