Creating a filter: Example
This example shows how to configure filters to scan any removable drives (including all currently inserted USB pen drives) as well as the folder D:\Custom\.
In order to create such a unit, two Include filters must be specified, one enabling the scanning of all removable drives, and the other enabling the scanning of the custom folder. If we were to create a single filter combining both scanning parameters, the logical AND operator would be applied, and such filter would only enable the scanning of the D:\Custom\ folder located on removable drives.
Create the first Include filter to scan any removable drives:
Clear the All Drives check box and all check boxes in this category.
Select the Removable, Floppy & Optical check box.
Select the All Paths check box.
Select the All Files check box.
Create the second Include filter to scan the folder D:\Custom\:
Select the All Drives check box.
Clear the All Paths check box and all check boxes in this category.
Enter D:\Custom\ in the Path field under Custom.
Select the All Files check box.
