Well, on this MS Windows XP pro installation this information seems to
be stored in the .newsrc.eld file. I've not found an active file.

Sounds like a lot of work with more than 250 mail dirs. ;-)

I solved the problem now by editing the .newsrc.eld file:

- 'C-u ESC-x shell-command-on-region ls ~/Mail/mail'
  (to get listing of my email dirs into the .newsrc.eld file)

- now I wrote a keyboard macro to change the dirnames into group
  entries, eg.:
  
  adrian_otto 

  to 

  ("nnml:mail.adrian_otto" 3 nil nil "nnml:")

- then I used apply-macro-to-region-lines to convert all lines with
  dirnames 

That did the trick for me. But I still wonder, if there is a simple
gnus command to do this.
