Stands for automatically executed batch file, the file that DOS automatically executes when a computer boots up. This is a convenient place to put commands, such as date and time, you always want to execute at the beginning of a computing session.

An automatically executing DOS/Windows batch file in the root directory of the boot drive that is concerned with system configuration. It is executed directly after the CONFIG.SYS file finishes executing its commands. Some computer configurations do not use this file.

This is a special file in most computers which is used to start up (Boot) your computer. It's already in there, so don't worry about it.

A batch file created at the root of the disk during DOS installation for most recent versions of DOS. It can also be created or edited with a text editor. It executes when the computer is booted, automatically loading files. It also can be used to log the user into the network.

A DOS batch file that instructs the computer at boot-up what actions you want it to perform. In DOS it is one of the first files opened and executed. This is a plain text file, but must be written in the proper format in order to operate. For a sample file see Partitioning and Formatting set-up procedures.

A special batch file used by DOS and OS/2 when booting up the computer. If DOS finds the AUTOEXEC.BAT file, it automatically carries out the commands contained in the file. Back to the Top

The AUTOEXEC.BAT file resides on all PCs and contains a series of commands that are executed when the computer starts up.

This is a configuration file which the operating system executes every time it is started. The easiest way to change the configuration parameters in the AUTOEXEC.BAT file is to use the SETUP program.

A special file containing instructions that are carried out every time the computer system is started or re-started. These instructions help the computer get set up and find certain programs.

A file in MS Disk Operating System that contains instructions that affect any subsequent running DOS programs.

n. A special-purpose batch file (set of commands) that is automatically carried out by the MS-DOS operating system when the computer is started or restarted. Created by the user or (in later versions of MS-DOS) by the operating system at system installation, the file contains basic startup commands that help configure the system to installed devices and to the user's preferences.

The second file executed when a computer using DOS is finished booting (after the Config.sys file). It contains system configuration programs that control the mouse, network card, prompt, and DOS environment profile.

In DOS and Windows based PCs, the file that contains a list of commands that are auto matically exec uted on system start up.

A file that DOS reads whenever you boot or reboot your computer. This file contains a series of commands that DOS automatically executes.

A startup text file once used by DOS and used by Windows to provide backward-compatibility. It executes commands automatically during the boot process and is used to create a 16-bit environment.

In a DOS system, set of commands executed at each system initialisation (either after power-on or after pressing Control+Alt+Del). This file is restricted to the use of the system administrator. In a PMF system, the AUTOUSER.BAT, executed immediately after the AUTOEXEC.BAT, can be accessed and modified by the user.

A batch program (set of commands) that is automatically carried out by MS-DOS whenever the computer is started or restarted. The file contains basic startup commands that help configure the system. Often, when a computer stops doing what it normally does when it boots (enters dos shell automatically or starts Windows, etc.), it is because the autoexec.bat file has been deleted. It is a good idea to have a copy of the autoexec.bat file (printed or on a separate disk) in case this happens.

AUTOEXEC.BAT is the name of a system file found originally on the MS-DOS operating system. It is a plain-text batch file that is located in the root directory of the boot device. The name of the file is a portmanteau of the words "automatic" and "execution", which describes its function in automatically executing commands on system startup; the portmanteau was coined in response to the 8.3 filename limitations of the FAT file system family.
