DIR Command in Windows: Complete Practical Guide

The DIR command in Windows is the built-in CMD utility for listing files and folders, with options for filtering by attributes, sorting by size/date/name, and scanning recursively through subdirectories. It is one of the most used commands for diagnostics, inventory, and script workflows.

What Is DIR in Windows?

DIR is the default directory inspection command in Command Prompt. It helps you confirm file presence, inspect folder contents, and gather output for scripting or reporting.

Syntax

DIR [drive:][path][file] [/A[:attrs]] [/B] [/O[:sort]] [/S] [/P] [/W] [/T[:field]]

Parameters and Options

Option	Description
/A	Attribute filter (H, S, D, R, A)
/B	Bare list format
/O	Sorting rules
/S	Include all subfolders
/P	Pause page by page
/W	Wide compact layout
/T	Time basis (C, A, W)

Examples

DIR
DIR C:\Windows
DIR /A:H
DIR /A:-D /O:-S

Common Use Cases

• Verifying deployment files exist.
• Identifying large files that consume storage.
