CD Burning Question

I received the following question in an email last week:

I have recently started to implement the use of electronic portfolios using Microsoft Word with hyperlinks to digital media. Much of the work linked has been converted to PDF files and all works well until we try to burn collections to CD. Once a collection is on a CD and we click on a hyperlinked file, we get the "Cannot open specified file" message and the link is still referencing the original storage drive. Can you tell me how to avoid this?

Here is my response: Now you know why I no longer use Microsoft Word for ePortfolios. You might try GoogleDocs (the equivalent Web 2.0 tool). If you converted everything to PDF (including the portfolio) and hyperlinked the documents together (or put everything into a single PDF file with hyperlinks), you would solve that problem when you publish to CD. My instructions for creating PDF-based portfolios are online: http://electronicportfolios.org/portfolios/sitepaper2001.html (but that was published in 2001).

But even that process is ePortfolio 1.0. You really need to look at some new tools, but using the same strategies. I really like wikis and blogs or many interactive Web 2.0 tools. I have a web page that outlines the different options:

CDs are going away. Even DVDs are limited in the future. They aren't interactive environments. Read my description of ePortfolio 1.0 and ePortfolio 2.0: http://electronicportfolios.org/web20.html
Everything is moving to the WWW. Here is my latest proposal for a paper at next year's AERA (created/published in GoogleDocs):
