How to create a new folder

[t.zalezny]

I'm not sure to understand your problem but:
The root folder is UNIQUE. You can create a hierarchy of desired complexity of subfolder inside it using the command "add subfolder".
The structure is similar to a standard filesystem (a real one, don't think to windows virtual directories).

Yes I know that i can "add subfolder" however I would like to create several root folders. I would like to avoid this situation:

FOLDER
- subfolder1/ subfolder
-subfolder2/ subfolder

I would like to have it like that:
FOLDER
- subfolder
FOLDER
-subfolder,

I hope You understand what I', trying to say
