This bit below is from one of my first programs as I'm currently
learning. It is designed to go form the root down and return the full
paths of everything it finds into a list. (I then check the reults for
files paths that exceed a certain length - but you don't need to know
that.)


    def findallfiles(self, base):
        self.results = []
        for root,dirs,files in os.walk(base):
            os.chdir(root)
            self.scan = glob.glob("*")
            for r in self.scan:
                if root[-1] == "\\":
                    self.results.append(root + r)
                else:
                    self.results.append(root + "\\" + r)
        return self.results
