InformationSet Applications and File Types fields to any in WildFire file blocking profiles. With a WildFire license, seven file types are supported, while only PE (Portable Executable) files are supported without a license. For the 'web browsing' application, the action 'continue' can be selected. This still forwards the file to the Wildfire service, but also presents the end user with a confirmation message before they receive the file. Selecting 'continue' for any other application will block the file (because the end user will not see the prompt). If there is a 'continue' rule, there should still be an 'any traffic / any application / forward' rule after that in the list.
Selecting 'Any' application and file type ensures WildFire is analyzing as many files as possible.
