I think the multiple file numbers are for packages that are loaded with textures and stuff. The files probably had to be split up to make downloads easier. Haven't installed anything yet ... I'm too busy drooling over all of the renders. 8-)

As far as PP7 and the CD, I'll start up another thread so as not to divert this one.  I am happy to say, though, that my preview copy just arrived moments ago, and it looks great. It should be filtering down to the stores and online places soon, through distributors. You'll more than likely see it right around Christmas time!!!

More in another thread, soon to post ....
