Really for bind-users and not dns-operations...

But in response, those files are cached copies of the slave zones you are
serving. Bind will transfer and keep a copy of these zones to enable bind
to serve the data immediately on a restart, otherwise it would have to
perform a zone transfer on start-up and if the master is no longer
available then bind wouldn't be able to serve the zone.
