Which of the following commands is used to duplicate a directory from one location to another?

The MOVE command relocates files or directories from one location to another but removes them from the source, so it does not duplicate - it transfers.

The COPY command duplicates individual files but does not natively copy entire directory trees with subdirectories without additional switches.

XCOPY is an extended copy command that supports copying entire directory structures with the /S or /E switches, replicating folders and their subdirectories to a new destination. Unlike the basic COPY command, XCOPY was specifically designed for duplicating directories rather than individual files. It has been a standard Windows command-line utility for bulk file and directory duplication since early versions of DOS and Windows.

EDIT is a command-line text editor used to open and modify text files, not a file or directory management command.
