jenny, I have a large number of CDs for Poser--including all my animals. As you say, they take up a huge amount of HD, so I burn everything on CD's. I also organize mine very well before I burn them--in fact I keep a folder on my desktop with organized folders within it (i.e., Vicky, P4 female clothing, clothing props, etc.) and then I burn it when it hits 600 MB and/or once a month. I label it and keep one CD folder with nothing but 3D CDs--pretty easy to find things that way. I also have a CD-RW for Mike and one for Vicky so I have all their 'things' together (they are also burned on a regular CD). When I need something I go through my CDs--if I'm looking for P4 female clothing, for instance, I open all those folders starting at the newest CD. When I find what I want, I just unzip it and load it into the library, geometry, etc. BTW, if the zip title isn't explanatory enough, I rename it in my 'saved' folder on my desktop. The folders are named by date I start them--so I always have a current folder there to download to all month. Diane
