You can use the Template Organizer to manage your map templates.
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.
On the Template Organizer Map Templates tab, click the collection where you want to add the folder.
Under Folder commands click New.
Enter the name for the new folder.
Under Folder commands, the Delete and Rename commands 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, click its name and then use the commands under Template commands.
Favorite map templates show automatically when you start a new map using the From Styles and Templates command, 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.
On the Template Organizer Map Templates tab, click the template file name.
Select the Show wizard when creating new maps checkbox.
