What are you offering?

There are usually two ways to handle directory trees, recursive descent or building a list of unvisited nodes. Most file systems provide a method to enumerate files/directories in the current directory, higher level code is expected to perform any traversal. You'd want the file system to maintain context in such a way that multiple searches can be open at once.

Ok, so how are you traversing the directories now. Can't you just build a path as you descend? What limits you there? Need a deeper path keep allocating memory to accommodate it. What user interaction? What kind of file system, and on what media/hardware?

Help is not the same thing as doing it for you, if you want someone to write code you need a contractor/consultant.
