About policy folders
Policy folders organize and apply policies according to whatever criteria is most appropriate to your organization. For example, the Smoothwall Filter blocks all adverts for all users all the time in every location by default.
If you want to allow some users and groups to see adverts sometimes and others to see them always at specific locations, you can accomplish this by creating a policy folder that contains a general web filter policy allowing access to adverts. You can then add policies to the folder specifying the groups allowed access, at what times and in what locations.
Using policy folders makes it easier to understand the policy table on the Manage policies page and more accurately reflects how a policy is applied to specific groups. You create a policy folder by using a policy wizard.
