Yes, in essence that is what this is doing but I am not manipulating the 
DirectoryIterator objects.  I am instead using my own structure and logic to 
do this.

Basically I'm using normal (i.e flat) DirectoryIterator objects but when I 
encounter a sub directory, I instantiate another DirectoryIterator for the 
sub-directory to continue the iteration.  In order to remember where I was 
once I've finished iterating over the sub-directory the current iterator is 
pushed onto a stack.  Then once the iteration of the sub-directory is finished 
the iterator for the parent directory is popped off the stack and the 
iteration over that directory continues from where it was interrupted.

Does this explanation satisfy your question?
