File Manager is a file manager program originally bundled with releases of OS/2 and Microsoft Windows between 1988 and 2000. 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.
File Manager was reintroduced as an optional download for all modern releases of Windows (including Windows 10 and later) on 6 April 2018.
