I am creating a backup set for the first time, I am shocked at the interface. I want to be able to (de)select of folder and that apply to subfolders and I don't see it. Really? I have at least hundreds probably thousands of folders, I should be able to deselect at a top level and apply that to all subfolders.
When setting up a backup set, you can start by deselecting all the pre chosen file types that Norton wants to backup. Then click on Add or Exclude files and folders.
Then click on Included folder, or Include file to add the folders and files you wish to have backed up.
