If you’re new to programming you may not know what Recursion is.  Think file / folder structure in windows.  If you had to find every file in a folder and all it’s sub folders how would you do it?  Answer: recursion.

Here’s a handy little pattern snippit if you’re looking to do recursion on files / folders in .net:

        static void SomeRecursiveFunction(string sFolderPath)
            foreach (string sFile in System.IO.Directory.EnumerateFiles(sFolderPath))
                //Do work here
            foreach (string sDir in System.IO.Directory.EnumerateDirectories(sFolderPath))
