A Batch Script is a simple text file containing a series of commands that are executed by the command-line interpreter in operating systems like Windows. These scripts typically have a `.bat` or `.cmd` file extension and are used to automate repetitive tasks, such as file management or system configuration. By running a batch script, users can save time and reduce errors, as the script executes commands in sequence without manual input. This makes it a useful tool for both beginners and advanced users who want to streamline their workflows or perform complex operations easily.
