If the `File` is a symbolic link, it looks after all that for most methods, the final target of link is used. The methods where the link itself is used are `isHidden()` (Unix only), and `delete()`. Given this, perhaps a better approach would be to add a statement in the class specification that links are followed unless a method specification states the contrary?
