The folder content menus behave pretty similar to those of the WarpCenter. If you click on a folder menu, the respective submenu will open. If you click on another symbol, the respective object will be opened in its default view. If you click on a folder menu with mouse button 2, the folder window will be opened (instead of the submenu).
Please consult the XFolder Online Reference to read more details about these functions and how to configure them.
You may remove this menu item on the "Context menus" pages in the "Workplace Shell"
object and, for "favorite folders", on the "XFolder" page in a folder's settings
notebook.
