    WatchService watchService = FileSystems.getDefault().newWatchService();
    faxFolder.register(watchService, StandardWatchEventKinds.ENTRY_CREATE);
    faxFolder2.register(watchService, StandardWatchEventKinds.ENTRY_CREATE);


    boolean valid = true;
    WatchKey watchKey = watchService.take();
    for (WatchEvent<?> event : watchKey.pollEvents()) {
        WatchEvent.Kind kind = event.kind();
        if (StandardWatchEventKinds.ENTRY_CREATE.equals(event.kind())) {
            String fileName = event.context().toString();
