To set the maximum archive nesting level for content filtering:
In the application protection settings, the maxNestingLevel field sets the maximum depth for scanning archives. If you set this field to a value other than 0, the application will scan archives to the specified depth even if their nesting level exceeds the specified value. If no viruses or violations of limit set in content filtering settings are found down to the specified depth, the application will display the scanning result as "Clean".
