What Is a Batch File?
A batch file is a file that contains one or more commands to be executed subsequently. Instead of typing those commands in Command Prompt or PowerShell, you create a file that runs those commands whenever the file is launched. This lets you accomplish the tasks of those commands.
A batch file uses “.bat” as its file extension. You run batch files the same way you run other files—simply double-click a file to launch it. No third-party apps are needed to open batch files.
