    • From the Control Center, click Status > Hosts. Use the Hardware Information and Hardware Status tabs to see total disk space and current usage.

    • From the command line, type system-stats disk_used and system-stats disk_free

  2. If disk space is in short supply, you have the following options to free disk space:

    • Delete content informational and content quarantine incidents

    • Delete spam message quarantine items
