Flags are specially designed to help you avoid time consuming misfiles. When a file has been removed, simply raise the red flag to signal that a file is out and where it should be returned. The raised flag will not interfere with opening or closing your file drawer. Once the file is returned to its correct place, lower the red flag. Fits into the inserts of all hanging folders--no need to purchase new hanging folders.
