If I may ask just a little practical question to be able to completely 
understand  your  explanation :

A  folder "a" contains 3 folders "a1","b1","c1" and each of this 
folders contains another folder :  "a1" contains folder "a2", folder 
"b1" contains folder "b2" and folder "c1" contains folder "c2".

How many times your recursive handler is recursing?
