I've experimented with PPTX files and included PDFs. PowerPoint automatically creates a bitmap version of included PDF files. If I just use zip tools built into my MacOSX finder I can unzip the PPTX, find the bitmap objects and remove the files. I then zip back up the PPTX. When I open PPT automatically generates a bitmap version for each PDF in my PPTX. There is no warning, it just does the fix up. I wonder if the same happens if the EMF version of an embedded XLS is deleted. I wonder if that is true for PPT and PPTX files?
