What is a batch file or .bat file
A batch file is a text file that contains a sequence of commands for executing in a computer operating system. It batches multiple executables commands into a single file and executes all at once. A batch file is usually created for command sequences for which a user has a repeated need. Commonly needed batch files are often delivered as part of an operating system.
