ok....how big is the file you are saving. Also you can always rename the bak file to .vue and try to load it. Grouping is also a very improtant thing to remember as well as hiding layers. It will save them faster and easier, as well as load them next time. I had a file once that was only 100mb, and around 8mil poly's it took it almost 15 minutes to save the file. Dont get in a hurry, as sometime depending on what you have in the file, it can take a very long time to save it. Hope this has helped you. James
