[FLOW3-general] Sub folder in Controller

[Martin]

Dear List,

how can i access a subfolder in Controllers?

I want to organize my controllers a little bit, but we don't become friends.

What do I have to do, to get for examlple 
Controllers/Administration/AdministrationController running.

In the View I tried: <f:link.action action="index" 
controller="Administration[/,\]Administration" 
 >Administration</f:link.action>

And calling it directly is also not working.
I also tried to put up a subroute but I am not familiar with routes ether.

Cheers Martin
