We all have computer files we'd like to keep secret from the world, but not everyone knows how to password protect a folder in Windows 10. Whether you're hiding notes from someone with access to your computer or (hopefully) something less drastic, you're allowed to have some privacy. Fortunately, in Windows 10, you can tuck those unmentionable plans or files in a secret folder that is password protected, and you can do it without buying any additional software. Once you've created a new folder in Windows 10, here's how to password protect it.

A note before you start:

We've received comments about issues people have run into with this how-to. So, we went back and performed multiple rounds of testing internally, and can now confirm that following this process closely, step-by-step, works — at least on our end.

But just to be safe, you should first try this how-to using files that you can afford to lose, just in case the method doesn't work for you. Also, make sure you're keeping some record, somewhere, of the exact password you're using to lock your folder. If you lose the password, your files are gone, and since every computer is different, we can't deduce exactly what went wrong on your end.

Also, yes, the FolderLocker file can be reverse engineered by someone who understands the process, but this isn't meant to keep tech-savvy folks out, just nosy family members who you don't trust.

Tips from readers:

Do not use a password with a space, it may create an issue with the batch file.

Yes, files placed in your locked folder can appear in Recent Files list in various apps, such as Microsoft Word.

Here's how to password protect a folder in Windows 10, so you can fill it with files you want to keep secret — and how to lock it, open it and repeat.

How To Lock a Folder With a Password in Windows 10

6. Paste the below text into the new document:

cls

@ECHO OFF

title Folder Locker

if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK

if NOT EXIST Locker goto MDLOCKER

set/p "cho=>"

if %cho%==Y goto LOCK

if %cho%==N goto END

echo Invalid choice.

goto CONFIRM

:LOCK

ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"

attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"

echo Folder locked

goto End

:UNLOCK

echo Enter password to Unlock folder

set/p "pass=>"

if NOT %pass%==Your-Password-Here goto FAIL

attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"

ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Locker

echo Folder Unlocked successfully

goto End

:FAIL

echo Invalid password

goto end

:MDLOCKER

md Locker

echo Locker created successfully

goto End

:End

7. Find where it says "Your-Password-Here" in the document.

8. Replace "Your-Password-Here" with the password you want to lock the folder with.

9. Click File.

10. "Select Save As..."

11. Click on the "Text Documents (*.txt)" menu bar that's next to "Save as type:"

12. Select "All Files"

13. Change the file name to "FolderLocker.bat"

15. Double-click FolderLocker.

The Locker folder has been generated!

16. Fill the Locker folder with the items you want to protect.

17. Open the FolderLocker file, because it's time to lock that folder up!

18. Type "Y" into the screen.

19. Click Enter, and the Folder Locker window will disappear, along with the Locker folder itself! Your secrets are safe!

To unlock the folder, double-click "FolderLocker" to open it.

Enter the password you entered in Step 8, and click Enter.

The Locker folder is back. You can open it to find your hidden files. Repeat Steps 17, 18 and 19 to lock the folder again.
