Often, you might plug in a USB pen drive and notice that folders have turned into shortcuts or files seem to have disappeared. In many cases, your data is still there—just hidden by certain file attributes (Hidden, System, or Read-only). The built-in Windows attrib utility can remove those attributes and make your files visible again.

Quick answer: the attrib command to unhide pen drive files

To unhide files on your pen drive, open Command Prompt, verify the correct drive letter for your USB, and enter:

attrib -h -r -s /s /d X:\*.*

Be sure to replace X with the actual drive letter assigned to your pen drive in This PC. Never guess the letter.
Warning: Always double-check the drive letter before pressing Enter. Never run this command on C:.

What the command does:
- -h removes the Hidden attribute
- -r removes the Read-only attribute
- -s removes the System attribute
- /s applies the changes to all files in subfolders
- /d includes folders/directories
- X:\*.* targets all files and folders on the specified drive
After running the command, refresh your USB drive window. If files are still missing, check File Explorer > View > Show > Hidden items. If you still can’t see your files, there’s a chance they’ve been deleted, not just hidden.

Common Causes of Hidden Files:
Cause Description

Shortcut Virus

Malware hides files and replaces them with .lnk shortcuts.

Accidental Hide

Files were manually set to "Hidden" or "System" attributes.

Antivirus Cleanup

Antivirus removed the virus but left the hidden attributes untouched.

FAQ

Is the attrib command safe to run on a pen drive?

Yes, it’s safe. The command only changes file attributes (Hidden, Read-only, System); it doesn’t affect file contents. The main risk is accidentally using the wrong drive letter, especially C:. Always confirm the pen drive letter before running the command.

What should I do if I get an 'Access denied' error?

Try running Command Prompt as an administrator:
1. Press Windows + S, type cmd.
2. Right-click Command Prompt and select Run as administrator.
3. Enter the attrib command again.
If you still get an error, check if your USB has a physical write-protection switch or try a different USB port.
