A multifunction device displays a plurality of selectable user interface objects on the display. In response to detecting the first input, the device moves a first object in the plurality of selectable user interface objects across the display to a location on the display that is proximate to a second object in the plurality of selectable user interface objects. In response to detecting that the first input meets predefined folder-creation criteria while the first object is proximate to the second object, the device creates a folder that contains the first object and the second object.
