I can think of 2 possible reasons for your problems. I'm not sure that I completely understand your underlying problem, so I'll list both.
Possibility 1
Have you considered producing a setup/installation file? You do this by:
1. Publishing your pub as normal.
2. When this finishes, instead of chooing the default option to
Return to the Opus Editor, select
Create a setup program for distribution and click the Finish button.
3. Choose your options and click Next.
4. The next screen contains an option that allows you to
add additional files. Click Add files or Add directory.
5. Continue until you have listed all the PDF files. Click Next.
6. Continue making selections relevant to your project.
On completion you will have a single setup file which will install the publication exe and all your pdf files into the single installation directory chosen by you.
Once you have done this, your pub should have access to all your pdf files.
Possibility 2 -- less likely
For a variety of reasons, you will find that several Opus designers, in recent years, have had problems using PDF files. The biggest problem I encountered was various incompatibilities and restrictions in using
older versions of PDF documents with more recent versions of Adobe Reader.
For that reason, I switched to using a nifty little program called PDF2EXE which is available from
http://www.pdf2exe.com/. There is a free version, plus a Pro version. Using this, it is simple to convert any PDF file to an EXE, and because the resulting exe includes its own PDF viewer, I've avoided all the problems that were bugging me.
