Explanation:
From the Storage Reports Management node, you can generate reports that will help you understand file use on the storage server. You can use the storage reports to monitor disk usage patterns (by file type or user), identify duplicate files and dormant files, track quota usage, and audit file screening.

Before you run a File Screen Audit report, in the File Server Resource Manager Options dialog box, on the File Screen Audit tab, verify that the Record file screening activity in the auditing database check box is selected.
