For Theatre Manager to run optimally there should be at least 10% free space in the database. This will result in faster access and manipulation of the database as well as greatly reducing the chances of sector overruns which result in freeblock damage. Theatre Manager can be setup to run a check to ensure the database has enough free space to run optimally. Click Here to learn how to setup an automatic check.
