Thanks for the example. I used it to test the readers on my Win7 desktop computer and was able to extract the downloads with: Adobe Acrobat Reader DC, Pdf-Xchange Viewer (free v2.5 2012), and Sumatra 2.3.2. I like this approach. I doubt that I could use this for a paper with a traditional journal but who knows?? I also post papers to ResearchGate etc and there it would work since you just have to post a pdf. I don't know whether it would work on arXiv where they want tex files but it is also worth a shot. So how do I implement this with Lyx? You mentioned to use the "Navigator' package. I looked at the documentation and AFAIK it allows including links to stuff but it is not clear how to add an attachment. I would appreciate help in getting attachments working from a plain-vanilla install of Lyx. Bob
