It is a single-instance graphical interface, replacing the command-line interface of MS-DOS, to manage files (copy, move, open, delete, search, etc.) and MS-DOS Executive file manager from previous Windows versions. Although File Manager was included in Windows 95 and Windows NT 4.0 and some later versions, Windows Explorer was introduced and used as the primary file manager, with file management via a two-pane view different from that of File Manager, and a single-pane view obtained by clicking a "My Computer" icon.
