Actually. I unzip everything then save it to CD. Because CD's are really cheap now. And I don't wan't the hassle of unzipping things later when I want to install the files. I give everything it's own folder. a)geometry b)library c)texture All have there own folder so I can Just copy and paste them straight from the CD to the HD. I find it very fast and since the folders are all labled. I know exactly what's in them before I open them. This takes up more room using folders for everything. But it's very organized. And like I said. I can get a pack of CD's for six bucks. So it's worth it to me because it's fast and convienient. ScottA P.S.- I always save extra stuff like .phi,txt, files in the figures geometries folder. That's a habit of mine. Others may wish to put the stuff in another folder. Just be consistent and you should be good to go.
