In MS-DOS, which command moves a file from one directory to another (optionally renaming it at the destination)?

Introduction / Context:
Relocating files between directories is a routine administrative task. While copying duplicates data, moving transfers the file to a new path and removes the original, saving space and keeping a single, authoritative copy.

Given Data / Assumptions:

• Source and destination directories exist and are writable.
• User wants to relocate, not duplicate, the file.
• MS-DOS MOVE utility is available (included in later DOS versions and Windows DOS boxes).

Concept / Approach:
The MOVE command changes a file’s directory entry to the target location, performing a rename across paths (and physically copying then deleting if required across volumes). COPY leaves the original in place; RENAME changes the name within the same directory only. CP is a UNIX command, not DOS.

Step-by-Step Solution:

Verification / Alternative check:
Attempting the same operation with RENAME across directories fails, confirming that MOVE is required for cross-directory relocation.

Why Other Options Are Wrong:

• COPY: Duplicates without deleting the source.
• RENAME: Renames in-place within one directory.
• CP: Not a DOS command.
• None of the above: Incorrect because MOVE is correct.

Common Pitfalls:
Forgetting to include a trailing backslash on the destination directory or omitting quotes when paths contain spaces in later DOS shells.

Final Answer:
MOVE
