Quote - Things within the folder have different locations, so they can coexist peacefully.

This is the crucial point - you may have nailed it there. I think that I can trace the problem back to the actual installation process. When I click on the install icon it fails to recognize the DS application folder and also gives me no option to direct the installation into it. Instead it creates a folder on the Hard Drive called runtime and puts all items into this. The software I can access (and use) is within the content folder of the application itself - this is Vicky, the fairy outfit and woodland scene. I notice, however, that within the application's runtime folder, only texture elements are stored. All other elements are dispersed throughout the content folder in, presumably, a correct manner - where they should be. What happens, when I direct the software to "add content" from another runtime folder, (within another named folder, as you suggest) is that it can then find the new stuff and list it all in the contents panel - but when I try to select and use it, nothing happens. I assume this is because the various components that make up a figure are not in their correct locations within the application folder, so the software cannot access the relevant data in the relevant place. I'm very used to installing all kinds of software and I feel that therein lies the problem. The various components of the new items are simply not in the correct locations for DS to be able to access them. I may be wrong here but it seems odd to me that the 'working' software is distributed around the applications folder in some kind of logical manner, whereas all components of the new stuff are just lumped together in one new 'runtime' folder. There isn't a lot of software out there that could make sense of that IMHO.
