Doesn't that have the same problem? We really need to have either a convention that filenames that do not completely match the syntax are always passed on or we need to move to one singe file handler that dispatches to the right backend. Or even both. As the one who wrote the origional messages and who picked the subject I can say that this is the matter I wanted to address. Jan
