Iterating through a file structure

Question

If I have a directory structure like so on a web service that sends me a list of files and folders in the directory I request. How would you go about iterating through the entire structure. There is no recursive search, so each directory has to be pulled one at a time. I can get the directories content I request but it doesnt list any sub-directories information. I was trying to think of a way to do this with a for loop or for each loop, but I havent been able to come up with anything. I didnt write the web service so I cant include recursive directory searching in it.

So you have to do the recursive search at your end then. For each directory you have in the response list, you then call again to request the contents of it. the same logic applies as to if you were doing the recursive search on the file system directory — musefan, Nov 08 '12 at 14:27
I think this is a legitimate question and I'd like to know why this has been downvoted. Does the downvoter care to comment? — Dennis Traub, Nov 08 '12 at 14:37

Your probably looking for a Tree Traversal Algorithm:

The first one is a Recursion based Algorithm and probably what ios85 is searching – Sven Hecht Nov 08 '12 at 14:29
