'''<code>AUTOEXEC.BAT</code>''' is a system file that was originally on [[DOS]]-type operating systems. It is a plain-text [[batch file]] in the [[root directory]] of the [[boot device]]. The name of the file is an abbreviation of "automatic execution", which describes its function in automatically executing [[command (computing)|commands]] on system startup; the filename was coined in response to the [[8.3 filename]] limitations of the [[File Allocation Table|FAT]] file system family.
