Previous posts have suggested that DEVONthink will not import Microsoft Powerpoint presentations. But, given that (at least for me) a large amount of information on my computer is in Powerpoint, how about the following work-around?
Powerpoint X is able to export an entire presentation into HTML, with one front .html page, and a folder containing all the images and additional .html pages.
Anyway that DEVONthink may be able to import that kind of structure, keeping the images intact and viewable?
