Difficulty: Easy
Correct Answer: COPY FILE1+FILE2 FILE3
Explanation:
Introduction / Context:
Older DOS workflows often required concatenating text or binary segments into a single file. The COPY command can join files using the plus sign, provided the syntax is correct and you understand implications for text versus binary data.
Given Data / Assumptions:
Concept / Approach:
The DOS COPY concatenation syntax is COPY fileA+fileB destination
. This writes the combined stream into the destination file. For text files, ensure proper end-of-file markers and line endings. For binary files, be cautious: concatenation is meaningful only when specific formats support it.
Step-by-Step Solution:
Verification / Alternative check:
Using TYPE FILE3
for text files will show the merged content. The DOS help for COPY demonstrates the plus syntax for joining files just as shown.
Why Other Options Are Wrong:
Common Pitfalls:
Concatenating binary files without understanding format; forgetting that COPY may add end-of-file characters for text in some DOS versions; overwriting an existing FILE3 unintentionally.
Final Answer:
COPY FILE1+FILE2 FILE3
