Since mine is 48.9 gigs, the flip answer is 'no'. Which version of Poser are you running? IF P4, then you will need a 3rd party app like P-Booost to do the multiple runtimes. P5 and above, you need to click on the file folder at the top of the library panel until you get to the top of the stack. It should have one folder with a red 'led' dot to indicate the runtime of the actual app is selected. All you need do then is click on the + sign at the bottom, which brings up the add runtime dialog, and find the folder (or folders, but you may want to start with one to begin with) you want to add. Select it and hit the ok button, and you should see a new folder with that runtimes name. Double click on that one, and the active dot should move to it. One little speed up trick if you are just starting out is to create and empty folder for the runtime you want, select it, then shut down and restart Poser. It should recreate the directory structure of a runtime for you (the geometry, libraries and those nested folders, texture folder, ect), so you should be able to unzip content straight to the initial folder, and things will go where they belong (always have a temp folder handy, though; there are still a lot of folks who zip a freebie from the Poser directory, not the runtime directory, so things get installed in the path Poser/runtime/ etc) Another speedup for starting Poser is to create a folder called null runtime and get into the habit of switching to that one whenever you shut down. Poser reads the entire selected runtime tree upon start up, and if there is nothing in the runtime to read, it goes on its merry way. -How- you break things up is going to be up to you. A few ideas to ponder; Remember you have to have the DAZ INJ-REM files in the actual runtime of the Poser app....but nothing says you can't keep them in your extra runtimes, as well. Get in the habit of keeping multiple copies, and you don't have to worry about reinstalling those: just copy them out of a remote runtime. It takes some surgery with notepad, or something like CR2 Edit or one of the other programs like it, but keeping the textures in =one= location will be more than worth the trouble, particularly if you render in other apps. My personal opinion is that you should separate out categories; make one runtime nothing but architecture. One for DAZ figures. One for the other figures. One for dynamic clothes and hair. If you have a lot of one style of clothing, create a runtime for them. But this is your runtime, so you need to arrange the resources to fit your workflow.
