I've nothing to say about the folder, but I hope this is a good place to bring up some thoughts about your option for viewing files in 3D.
I've tried it a few times and come to the conclusion that it absolutely will not work for me. It makes me click OK to download java things from two different locations, takes forever to load and then just displays a black rectangle.
I'm using Windows XP Firefox 2.0.0.3, and never use any other browser.
I might also pass on that I block flash by default, (watching YouTube videos requires one more click from me than it does from the average viewer.) and most videos or things that move have a tag appended to them so that I can block them if they bother me.
I think a better solution for displaying an object in 3D might be a Quicktime 3D movie rendered by your servers, or even a turntable gif animation. These solutions might be a lot more accessible and predictable than serving a 3D object, which can probably be quite large in some cases.
