What does the Manage File Extensions Utility do?
The Manage File Extension Utility is where you define File Extension Groups for use in TTC’s File Extension Sets. A File Extension Group is a list of file extensions that a File Extension Set references (and tells the Content Filter to block when a user attempts to download content matching the set.)

1. If creating a new group, click the “Create a new group” link and name it. If editing an existing group, select it from the “Select a group” pulldown.
2. Type in a file extension you want to include in the group.
3. Click the “Add” link. Repeat steps 2 and 3 until you’re finished adding extensions.
4. Once you’re done, TTC automatically saves the Group for you. You can now reference the new File Extension Group within a File Extension Set.

The following explains the major links and components of the Manage File Extensions Utility:

• Create a new group - Click on this link to create a new File Extension Group.
• Cancel - Click this link to stop creating a new File Extension Group.
• Select a group - Use this pulldown to view or modify an existing File Extension Group.
• Delete - Once you’ve selected a Group, you have the option to delete it. Click on the “Delete” link to delete the selected File Extension Group. Use this option with caution as deleting a File Extension Group referenced by a File Extension Set and Content Filter Property Set may cause unexpected behavior.
• Add a new extension - Type new extensions into the space provided to add them to the specified Group. Include the period as part of the extension (e.g. ‘.exe’).
• Add - Click the “Add” link to add the newly typed extension to the Group.
• Remove Selected - If you want to delete an extension from the group, select the checkbox of the extension and click the “Remove Selected” link.
