I don't remember if I posted this here or not. So here goes Here's something I've learned about user libraries. Say you create a new user library then fill it up with objects. Latter on you decided you no longer need some or all the objects in that library, so you delete them. Cool their gone, but according to your computer hard drive that library still reports being the same size. I had a user library I used to put objects in while I work on scenes, after the scenes are complete I delete the objects to keep what Bryce has to load when launched down, plus clearing hard drive space ( so I thought ) after I deleted all the objects in the library it still reported being close to 1GB. So I would suggest keeping a user library completely empty and use it for creating new libraries only. And when you need to house clean libraries you can move needed objects to other libraries and delete the whole library from the hard drive, with contents no longer needed. Other wise it's just a matter of time before your user libraries get out of hand, because just deleting items out of the library doesn't subtract from it's file size.
