Well, you could have left the template runtime. The folders from Zane would have just placed themselves in the corresponding folders when you dropped Zane's runtime over the template runtime. Windows will put then where they need to go. If you're on a Mac it's quite different and it's not really safe to do that.

You can change the names of folders if you REALLY think it's necessary; however, NEVER change the name or location of the textures folder or the texture files. Those all have absolute paths. You may set up your external runtimes the way you like. I have mine set up by figure. Some set them up by type (Poses, Figures, Props) etc. Some have them set up by vendor. You can set them up any way that works best for you.

Anything that's in the pose folder (body variation) is a morph. All morphs are in the Pose folder. Things called MAT files are also in the Pose folder. Those are special poses that apply textures.
