Confusing CC my work area

Why is it possible to organize CC files into folders only for Synced files and Cloud documents and not for Published files? What's the difference between Cloud documents, Synced files and Published? Both Published and Cloud documents are files placed on the CC server - so why the different names? Why is it only possible to see Cloud documents and Shared with you in the CC desktop application but not Files and Published? All of them are listed in two different menues in the CC application. And why does Shared appear two times in the CC desktop application? It's both inside and outside the menu, as the only option that is presented both places. This whole creative cloud system is so messy and confusing.
