In an electronic file system, preview information is provided to the user
during a drag operation of a selected object onto a target object. The
information indicates what type(s) of action is to be taken should the
selected object be dropped onto the target object. The action(s) to be
taken may depend upon the type of the selected object and/or the type of
the target object. For example, where the selected object is an item and
the target object is a persisted auto-list, the action may include
adding, removing, or modifying one or more properties of the selected
object to conform to one or more criteria defined by the persisted
auto-list. Also, numerical feedback may be provided to the user where
multiple objects are selected. For example, where seven objects are
selected, the textual number "7" may appear next to the cursor.
