Drag and drop is used pervasively in Windows for moving or copying files. Windows Explorer fully supports drag and drop, and for many users this is the preferred method of working with files. In addition, many users are accustomed to dropping files onto an application to open them — for example, dragging and dropping a .doc file onto Microsoft Word.
In this example drag and drop is used to populate a ListBox control with a list of files dragged from Windows Explorer.
