I do the same by clicking on the PDFs in the RAVE folder that I need. I also renamed the PDFs for easier searching.
I do this on my Mac and Windows computers with a current version of Acrobat Reader.

Click to expand...

Tried that but just got the message "The document is encrypted by an unsupported document handler"

Perhaps the fact that I am running RAVE from a mounted iso makes a difference. What I did not try was mounting the iso, copying the PDFs to the hard drive and opening from there. Seems an obvious thing to try, but it did not occur to me until I had already resolved the problem. Thanks for the help everyone.
