(As in – AUTOEXEC.BAT)
.BAT is a file extension used by computers to process batch files. Or to be a little more precise DOS Batch files which are used to execute commands from the DOS Box or Windows Command Prompt (cmd.exe).
I just realized that I’ve used the acronym DOS three times already without calling out what that means. DOS stands for ‘Disk Operating System’ and believe it or not, back in the day, you used to be able to boot a computer with a single disk or “Floppy Disk’.
Now, back to Batch files…
A file with a .BAT extension is essentially a text file that contains a series of line commands also in plain text that are executed to perform various tasks, such as starting programs or running internal commands or utilities within Windows. (paraphrased from – fileInfo.com)
