I have some docs I made 2 years ago that I now need to edit, and this mac doesnt' have the software, and I also can not remember the software's name. The extension is .xmap, which is too generic to be useful. The application itself allowed you to draw these hierarchal maps of various organizations. It's not unlike OmniGraffle or GraphViz. I'm fairly certain the software was included in one of those MacUpdate or MacHeist bundles from 2008. The app itself may have started with an X. ???
