I actually bought a harddisk to dedicate to 3D - and created runtime folders for Kids, Vickies, Mikes, House, Industry/Vehicles, Fantasy. Works great even on my lan when I am working from laptop - can access the same libraries as when I am on my desktop. Had a bit of problems with V3 so just upgraded my runtime for V3 base character/morphs in P5 runtime then the Vicky/Stephanie libraries ran just fine from the other harddisk. Why? I dont know.... Is nice to know where all items are; as like with clothes - I did subdirectories off of clothes directory for different characters (like female). Subdirectories off of Vicki for V3, V2, HiModel, etc.
