A CMD file is a script file used by the Windows command interpreter (cmd.exe). It contains a series of commands written in the Windows Command Scripting language, a scripting language designed for automating tasks within the Windows operating system. These scripts can be used to perform a wide range of operations, including file manipulation (copying, moving, deleting), program execution, system configuration changes, and network operations. CMD files are similar to batch files (.BAT), but they offer some enhanced features and capabilities, such as improved error handling and more complex control structures. They are commonly used for automating repetitive tasks, creating installation scripts, and performing system administration functions. The command interpreter reads the commands in the CMD file sequentially and executes them one by one. CMD files are an essential tool for system administrators and power users who need to automate tasks and manage Windows systems efficiently.
