Is there a written document on C5 admin usage. What's on line has tons of functions calls, which I assume isn't for a User/Admin.

Basically, I'm trying to find a Admin/User doc on how to use the FileManger, especially File Sets. I've created a File Set, selected it, but the upload function dumps the files in the general area.

So far, this hasn't been very intuitive. Hoping some writeup without forging through entry blogs will help.
Thanks
