which variable determines the behavior of news' drafts?

[Easior]

Hi, all.

I have made some modifications of default places of gnus directories, e.g.

(setq gnus-default-directory "~/.emacs.d/gnus/")
(setq gnus-home-directory "~/.emacs.d/gnus/")
(setq gnus-directory "~/.emacs.d/gnus/News/")
(setq message-auto-save-directory  "~/.emacs.d/gnus/Mail/drafts/")

it always works well. However, there exists a seemingly strange directory

$ cd ~/.emacs.d/gnus/News
$ ls 
agent  drafts trash
$ ls drafts
drafts queue

it means that there are two directories with the same name "drafts" exiting in 
the gnus
hirarchical directories. How can I do?

Thank in advance.
