Creating custom file types

You can set up custom file types to meet your organization's needs. For example, you might want to block a file extension not covered by the supplied file types, or create a type that groups a number of specific extensions.

You can also use custom file types to set up attachment blocking for MIME types.

To create a custom file type:

Go to Account > Custom File Types.

Click Add.

In the Extensions field, enter the file extensions to include in the custom type, separated by commas. For example, to block particular types of image file, you might enter JPG, GIF, PNG.

Enter any MIME types in the format content type/content subtype. For example, video/mpeg or text/csv.

Enter a description for your custom file type. This description appears in the Custom File Type list when you are selecting file types and formats for attachment quarantine.

Click Submit.
