What does the command RD do?

The command RD (or rmdir) is used in command-line interfaces like Windows Command Prompt to remove directories. It deletes an empty directory, and if the directory contains files or subdirectories, it will return an error unless the /S flag is used, which allows for the removal of the directory and all its contents. Always use caution with this command, as it can lead to data loss if used incorrectly.
