DOS Commands

DOS commands (Disk Operating System commands) are a set of commands used in the command-line interface of early Microsoft operating systems, such as MS-DOS and Windows 95/98. These commands were used to interact with the computer’s file system, manage files and directories, run programs, configure the system, and perform various other tasks.

Some common DOS commands include “dir” for listing the files and directories in the current folder, “cd” for changing the current directory, “md” for creating a new directory, “copy” for copying files, “del” for deleting files, and “format” for formatting a disk.

While these commands are not used as frequently in modern operating systems, they still have practical uses for system administrators, IT professionals, and power users who work with legacy systems or need to perform specific tasks that are not easily accomplished through graphical user interfaces.
