When you double-click on an element, you are offered a choice of actions to be carried out on the element, regardless of whether it is an image or a drive. If you want to have the selected action carried out every time this element is double-clicked, activate the Always execute the action selected here when this element is double-clicked option before you select the task. The next time the same element is double-clicked, the specified action is carried out right away, without first opening the action prompt. On the Task Assignments page of the Settings program, you can define or change the action to be carried out for an element as desired.
