You can use the Template Organizer to manage your map templates.
To see the organizer:
The template list shows all the available collections and the templates they contain. To further organize your templates, you may create folders within the collections.
To create a new folder:
Select the collection where you want to add the folder.
Under Folder commands click the New button.
Enter the name for the new folder.
Note: The Folder commands Delete and Rename buttons in this group apply to entire folders. If you delete a folder, all the templates it contains will also be deleted.
Move templates by dragging to a new folder or collection.
To modify, duplicate, delete or rename a template, select it in the list and then use the Template commands buttons .
Favorite map templates show automatically in the New - From Favorite Styles and Templates dialog, so if you have templates that you use frequently, add them to the displayed Favorites for instant access.
Some templates have wizards attached that automate map creation. If you select a template with a wizard, you can enable or disable it for new maps.
To enable or disable the wizard:
Select the template.
Click the Show wizard when creating new maps option.
