Overview
The Maintenance and Security Center (MSC) window contains all the tools needed for verification,analysis, maintenance, backup and compacting of data and structure files. The MSC is available in all the 4D applications: 4D single user, 4D Server or 4D Desktop. There are several ways to open the MSC window. The way it is accessed also determines the way the database is opened: in “maintenance” mode or “standard” mode. In maintenance mode, the database is not opened by 4D, only its reference is provided to the MSC. In standard mode, the database is opened by 4D.
