I have edited Poser4+Pro-pack down to the bare essentials - around 80 mb in total. As you have done Butch, I have removed all the P4 characters but the Daz Vicky/Mike/Milkids which I use. The only item I have kept is the Poser 4 Lo man as he is needed by the Walk Designer. I keep a zipped up copy of this basic runtime ready to drop in for any new project. My zips are burnt onto CD for safekeeping and I unzip them all and arrange them into ready-to-load runtime folders and then re-zip them onto a separate CD. I keep an excel file with a picture of what each contains with a hyperlink to each zip from the picture so I can quickly assemble a range of items for a particular project. Items like pose files I unzip and keep on disk and use PD3O explorer to locate what I want to use quickly. I am currently editing out P4 stuff from Poser 5 and keep only the P5 stuff and Victoria 3 on it. On a spare hard drive I have around 6-7 gb of textures/tools/etc. Props you can import from anywhere but I find my hair folder is still a little large.
