You can quickly remove unwanted folders from catalogs. 

  1. If you have multiple catalogs, make sure only the intended catalogs have Search and Add/Modify checked. 
  2. Select Browse.
  3. Use the Folder Path tree to navigate to the folder you want to remove. 
  4. Right-click on that folder and select Remove Folder

If there are any folders underneath your selected folder, they will be removed as well.
