Okay, sorry, I was confused. I thought I had checked out this program before and it only viewed PZ3 files, to show you what's inside the PZ3. Now that I've seen the (lengthy!) list of file formats this P3dO can view, I'm downloading to give it a try. I've got a bunch of nearly every type listed. It sure isn't just PZ3s! :) Laurent, one thing I can tell you about Vue d'Esprit, it might help, I don't know. There are two main types of files. Fox mentioned the VOB type. VOB is the object format. The other type is VUE, which is the scene file. (VUE is sort of like "PZ3" while VOB is sort of like "PP2".) Both VUE and VOB have preview images made when saved. So maybe it would be just a matter of being able to view the preview image, small thumbnail types stored with the file. Vue d'Esprit has its own file browser that displays the preview thumbnails. If you can still find a March copy of Computer Arts or an April issue of 3D World magazine, they each have a fully-functional version 3 copy of Vue d'Esprit. Then you could see what I mean. Download done! I hope to get some time tomorrow to see how your program works! :)
