To list hidden files in a directory and sort them by file size in Windows Command Prompt, use:

DIR /A:H /O:S

/A:H filters hidden entries and /O:S sorts by size from smallest to largest.

Why This Command Is Correct

The command combines two distinct controls:

Attribute filter: hidden files only.
Sort order: size-based ordering.

It directly answers common multiple-choice variants where other options use the wrong attribute or sort code.

Syntax

DIR [path] /A:H /O:S

Examples

DIR /A:H /O:S
DIR C:\Users\Public /A:H /O:S
DIR /A:H /O:-S
DIR /A:H /O:S /B
DIR /A:H /O:S /S

Common Use Cases

Hidden file audits.
Basic malware triage.
Checking hidden app cache growth.
Preparing file cleanup plans.

Tips and Best Practices

Add /A:-D if you need files only.
Use /O:-S for largest-first view.
Use /B before piping output.

Troubleshooting

No results returned

Directory may not contain hidden entries.

Directories included unexpectedly

Use DIR /A:H /A:-D /O:S pattern in staged checks.

Sort direction wrong

Use /O:-S for descending.

Access denied

Run elevated CMD in restricted paths.
