No, the files won't be converted to enhance compatibility with the new software. In fact, 3D Home Architect Deluxe is a discontinued product. It was available on Broderbund website in the past. Now, the new software is called Punch! Home Design Studio Complete and offers the same great features as Architect Deluxe did. You can browse the search result list at Broderbund website. You can either choose to use the old version (that you still have) or upgrade to the new one from the website mentioned here.
