(Files are usually depicted has having their points "dovetailed", while labels have longer, straight sided points.)

Now his rarely happens, but as a coat of arms is the personal property of the armiger, he may, within the terms of the destination of the original grant, choose to leave his undifferenced arms to someone other than his eldest male child. When this happens a file of three points is added as a permanent charge on the shield of the person passed over (in the instance of a Scottish chief a different cadency mark-- three eagle feathers-- is used) and the designated heir inherits the undifferenced arms. All other children retain their normal cadency mark.

In the examples shown above in both instances a label of yellow, or white would be appropriate.
