# MS-DOS subsystem commands

Windows XP includes 16-bit commands (nonnative) for the MS-DOS subsystem and other subsystems. These include older commands, such as edlin or graphics, and MS-DOS-specific commands, such as debug or exe2bin. These 16-bit commands are included to maintain MS-DOS and MS OS/2 version 1.x compatibility.

Other MS-DOS subsystem commands, such as share, perform functions that are now inherent to Windows XP or the MS-DOS subsystem. The commands are accepted to preserve compatibility with existing files, but they have no effect at the command line because the functionality is automatic.

Note

• The following 16-bit MS-DOS subsystem commands are not available on Windows XP 64-Bit Edition.
