the function of this script, is to distinguish wether the returned array is a file or directory, if it is a file, it generates a link to download the file, otherwise if it's a dir, it lists the files/dirs in that directory, works on windows _and_ *nix platforms, useful for mp3 sites... (also easy configuration)
