Create lists of file extensions so that you can use them in multiple malware scan configurations. A single list is easier to manage than several identical lists that are each created in a different rule. For example, one list of file extensions can be used by multiple malware scan configurations as files to include in a scan. Another list of file extensions can be used by multiple malware scan configurations as files to exclude from a scan.

See which malware scan configurations use a file extension list

It is useful to see which malware scan configurations use a file extension list to be aware of which rules are affected by any changes you make. For example, you can ensure no scan configurations use a file extension list before deleting it.
  1. Click Policies > Common Objects > Lists > File Extension Lists.
  2. Select the list and click Properties.
  3. Click the Assigned To tab.
