Does anyone know if Inkscape can open/import Micrografx Designer version 4 (.ds4) files? Unfortunately I don't have any such files, otherwise I would try it out myself (I hope to get some files soon, and before I do I'd like to know if I have to buy an old version of Micrografx Designer, now apparently owned by Corel).

I think I found the answer:
