Adding custom file types

Use the Filter Components > Edit File Types > Add File Type page to define custom file types.

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. Enter a unique File type name.

    You can create a custom file type with the same name as a pre-defined file type in order to add additional file extensions to the existing 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 type appears in the File Types 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.
