controller nested folders

[eluser]Jagar[/eluser]
Actually with the help of http://ellislab.com/forums/viewthread/107451/#541043 you can have unlimited nested folders, view the code.

You can either use the posted code, or use mine, which I customized it to fit my needs, it may even help you.

Code:
