Hello, To edit the templates in Version 10, it is not necessary to go in the template folder but you can just select in the program the template you want to customize and then click on duplicate. In this way if you doubleclick on the duplicated template it will open in the Template Editor Window where you can change the image files or the style of the template to adapt it. With this option you will always have the original copy of the standard template and it makes it easier to adapt it to your needs. Please feel free to write back if you need more information.
