tango.io.FileScan :).

If you're using Phobos, a recursive file scanner is pretty much the
easiest thing you can write!

Pseudo code:

scan(char [] Path, ref char [][] Paths) {
	Paths ~= Path

	if (!Path.isDirectory)
		return

	ListOfPaths = getContentsOfDir(Path)
	foreach (Item; ListOfPaths)
		scan(Path)
}

Obviously you can get more creative and store an array of structures
which contain file system information such as whether or not the path is
a file or a directory, etc, but that's the basic idea.

Even if you're not using Tango, you can always look at the source code
to see how they are doing it:

Hope this helps!
