There a several free ones available at many freeware sites around the net. Besides, file management and file types are a necessary evil for 3d software users that all newby's MUST learn. Another point is cross platform compatibality. you'd have to make two differant file for each machine type, which would clutter the free section even more. The final point that I would make is you get access to many models without the work. I takes you ten minutes to create a selfextractor and the "favore" you ask may take days or even weeks to create. Not a good cost benifit ratio.
