The document provides an overview of common commands used in the Windows command line interface (CLI). It describes commands for navigating directories (CD), listing directory contents (DIR), clearing the screen (CLS), creating (MKDIR) and removing (RMDIR) directories, renaming (REN) and deleting (DEL) files, copying (COPY) files between locations, and exiting (EXIT) the CLI. The CLI allows users to perform tasks like file/folder management from a text-based interface rather than a graphical user interface.
