File and folder administration

I'm looking to make a mirror of my machines file and folder structure in Files on my CC account but it doesn't seem to work at all. To me it looks like I'm forced to manually establish every single folder and add single files into those folders. There's now way to just copy what I have with folders and files and paste that structure in my CC folder. Example: I've made a folder on the CC Files section named XD and I want to copy all my folders and files into that folder. Why can't I do that?

Also, there's no way of adding folders to my Prototype and Specs section, I'm only allowed to add single files? Makes it very hard to work out an order or structure when I have 200 single files!

So what's going on? Am I doing something wrong?
