Acadia,
I was not aware of the fact that I could only delete the preferences file instead of re-installing the whole Poser 7 - But I am learning fast and will remember it.

I am using the second option that you have mentioned.
Firstly I can not install all my content as it uses too much space and I am not going to use everything. Sometimes I do want to get rid of something from my hard drive or I want to replace something with a newer or other version. Because I install everything now in it's own runtime I can at once uninstall something or add to it or whatever.

Some figures you can find under characters for example, while others you find under Pose, and some you find under!Mat Pose and some somewhere else. I am referring to the right hand side of Poser, the icon/thumbnail menu, where you can see what you want or can load. I refer to this menu that I duplicate in Collections, but which I can organise as I wish. Here, because I have duplicated the icons, I can organise it as I wish, under my own rules in any way as I see fit, as long as they stay in collections. I wanted to know if there is another way to do it without duplicating the files.

I think it will work if I delete the icons from the runtime libraries as I do have it under collections. In other words, if I install contents I must move starting icons to the directories where I want them under collections, and then they will only appear there and not under the default menu of Poser.

Regards
Johan
