Patricia, Chas is right. Poser 4 can't access folders within folders, unfortunately. What I do to over come this problem is use numerical folders. So, 01 - 09 are MATs for clothes : 10 -19 are MATs for hair, etc. You can name the folders '01 - vicki pants', '02 - vicki dresses', and so on. Basically you have from 001 - 256 to use, so you can invent your own system. Or use group names, like chas suggests, if that's easier. I tend to use numbers because the numbers more or less correspond in each library. So, in the faces library you can also have 01 - 09 for vicki expressions, or whatever figure you use most. One thing you can do, no matter what system you use is, when you're working on a new project or scene, you can rename the folders you'll be using to always have them at the top. My current project folders are always called '00 something'. That way, I don't have to hunt for them. 'I'm really dreading the 'housekeeping' I know how you feel. Believe me, the only way to beat it is to find a good system.... and alwaysw keep it updated. mac
