Adding file extensions to a file type

Use the Filter Components > Edit File Types > Add File Extensions page to add file extensions to the selected file type.

Important: Custom file types and custom additions to predefined types are used in extension-based enforcement, but not true file type analysis. See Enforcement based on file extension and Enforcement based on file analysis for more information.

Steps

  1. Verify that the expected file type name appears next to Selected file type.
  2. Enter file extensions, one per line, in the File extensions list. You do not need to include the dot (“.”) before each extension.
  3. Click OK to return to the Edit File Types screen. The new file extensions appear in the Custom file extensions list.
  4. When you are finished working with file type definitions, click OK on the Edit File Types page. Changes are not implemented until you click Save and Deploy.
