The Autoexec.bat file is a batch file located in the root directory that MS-DOS executes each time the PC boots up. It can contain commands to run programs or customize the startup process. Creating an Autoexec.bat file is similar to other batch files and involves using commands like COPY CON and DATE to write commands that will run on startup.
