"Which is why you never unzip/install a file to the runtime without first putting it on your desk top and looking through it.  It gives you a chance to move files and the rename folders."

That's what I do and everyone should. And put stuff you don't use much into a sub-folder and only have frequently used stuff in main folders. I have a folder named "other people" in which I put all the content for figures I rarely use. I search for content using Windows search within my Character and Props folders. If you name your folders and sub-folders logically, you can usually find what you want.
