Filename Lists

A Filename List is a list of one or more file identification masks. To use a defined filename list, select that filename list under the With A Filename Of section in a content rule's What To Look For? panel.

Create a filename list

  1. Navigate to Policy > Policy References > Filenames. The Manage Filename Lists page is displayed.

  2. In the Filenames panel, click New. An editing page for the new filename list is displayed.

  3. In the Overview panel, click Click here to change these settings. Edit the Name and Notes of the filename list as required, and click Save.

  4. In the Filenames panel, click New. The Add Filename dialog is displayed.

  5. Configure the Add Filename dialog:

    • Enter a filename. You may use wildcards according to the rules.

     

    Rules for using wildcard characters

    Use * (asterisk) to represent 0 or more characters.

    Use ? (question mark) to represent a single character.

    Examples of filename mask with wildcard:

    Filename mask Example matches

    *.zip

    (Any .zip file)

    b.gif

    *.xl?

    file1.xls

    file2.xlt

    *htm*

  6. Click Add. The new filename is added to the Filenames panel.

  7. Apply the configuration.

Edit a filename list

  1. Navigate to Policy > Policy References > Filenames. The Manage Filename Lists page is displayed, listing the existing filename lists.

  2. Select the filename list you wish to modify and click Edit. An editing page for the filename list is displayed.

  3. Modify the Overview and Filenames panels as required. Click Save on each panel to save your changes.

  4. Apply the configuration.

Delete a filename list

  1. Navigate to Policy > Policy References > Filenames. The Manage Filename Lists page is displayed, listing the existing filename lists.

  2. Select the filename list you wish to delete and click Delete.

     

    You cannot delete a policy reference, including Filenames (filename lists), that is currently used in policy route(s) or content rule(s):

    • A gray check mark () next to the name of the selected item indicates that it is not used by any policy routes or content rules.

    • A green check mark () next to the name of the selected item indicates that it is used by at least one policy route or content rule.

    To view which policy route(s) or content rule(s) are using the selected item, click Edit instead of Delete. The Usage panel at the top of the editing page shows which policy routes or content rules are currently using the selected item. Modify these policy routes or content rules accordingly to remove references to the selected item.

  3. Click Delete in the Confirm Delete dialog to confirm the removal.

  4. Apply the configuration.

 

If you change any configuration or policy settings, you must Apply Configuration for the new settings to take effect. You can do this either from the Changes Made panel, or System > Configuration > Apply Configuration. See Apply new configuration for more information.

If you use Peer Gateways (i.e. when multiple Gateways are peered), any configuration changes from a local Gateway can then be applied to all the peers at the same time. See Peer Gateways for more information.
