MS-DOS DIR formatting: Which switch causes the DIR command to display the directory listing in wide format (multiple filenames per line)?

Introduction / Context:
The DIR command in MS-DOS lists files and directories. Its behavior is modified by switches that control sorting, pagination, and layout. Understanding these switches is essential for efficient command-line navigation and file management.

Given Data / Assumptions:

• You are using the classic MS-DOS DIR command.
• You need the “wide” layout that prints several names per line.
• Other common switches may appear similar but do different things.

Concept / Approach:
DIR /W switches the output to wide format, suppressing file details and showing multiple columns of filenames. In contrast, /P pauses each screenful, /O sorts according to a specified order (e.g., /O:N by name), and /B uses bare format (names only, one per line).

Step-by-Step Solution:

Verification / Alternative check:
Run “DIR /W” and compare to “DIR /B” and “DIR /P” to observe differences in width, pagination, and verbosity.

Why Other Options Are Wrong:
/O: sorting, not formatting width. /P: pagination only. /B: bare format prints a single name per line, not wide columns. None of the above: incorrect, since /W is valid.

Common Pitfalls:
Confusing /B’s “bare” with “wide,” and assuming sorting switches impact layout; mixing pagination with formatting needs.

Final Answer:
/W
