My use case is pretty more complex but your advice works like a charm, which isn't surprising. Without abusing your time and patience, do you see a simple solution more fitted to a case where there are zillions "directories" at varying depths but only very few "files", that is without listing all the possible paths first and finally matching them the the files' directories?
