Purpose of the MS-DOS COPY command: What does the COPY command enable you to do?

Introduction / Context:
File management at the DOS command line relies heavily on COPY. Recognizing the breadth of scenarios where COPY applies helps users move, duplicate, and back up data effectively across devices and directories.

Given Data / Assumptions:

• COPY duplicates files from a source path to a destination path.
• Source and destination can be on different drives or machines (via mapped drives).
• Goal scenarios include transfer, backup, and media changes (for example, HDD to floppy).

Concept / Approach:

COPY accepts wildcard patterns, single files, or combinations (for example, concatenating text files). It works with any accessible drive letter, allowing movement between fixed disks, removable media, and network shares.

Step-by-Step Solution:

Verification / Alternative check:

After issuing COPY, DOS reports file(s) copied. Listing the destination shows the duplicates, confirming the operation across varied use cases.

Why Other Options Are Wrong:

• Each of A, B, and C describes a valid use case; therefore the correct umbrella choice is “All of the above”.
• None of the above: Incorrect because COPY performs all listed actions.

Common Pitfalls:

Overwriting files unintentionally without confirmation; forgetting to include wildcards correctly; confusing COPY with XCOPY (which is better for directory trees).

Final Answer:

All of the above
