I'm just curious to know under what circumstances where it's important to know whether a directory is empty it's also important that the operation occur with lightning speed... Reinhold's suggestion to delete the folder was interesting in this respect... isn't that (prior to deleting a folder) just about the only time one cares if it's empty, normally? And in this case you don't need to do the check, as Reinhard shows, so performance isn't an issue. -Peter -- http://mail.python.org/mailman/listinfo/python-list
