How to Password-Protect Folders on Windows Without Any Software

🔐 Your Privacy, Your Rules — No Apps Required

Whether you’re trying to keep sensitive files safe or just hide that surprise gift folder, you don’t need to install any sketchy locking software.
Windows has a built-in trick using a simple batch file that can lock folders with a password.

It’s not military-grade encryption, but it’s perfect for everyday privacy. Let me walk you through it.

🛠 What You’ll Need

• A Windows 10 or 11 PC
• Notepad (yep, that’s it)
• About 2 minutes of your time

🧾 Step-by-Step: Create a Password-Protected Folder

✅ 1. Open Notepad

Right-click on your desktop → New → Text Document
Open it and paste the following code:

cls
@ECHO OFF
title Folder Locker
if EXIST "Private" goto UNLOCK
if NOT EXIST "Private" goto MDLOCKER
:CONFIRM
echo Are you sure you want to lock the folder? (Y/N)
set /p "choice="
if /I "%choice%"=="Y" goto LOCK
if /I "%choice%"=="N" goto END
goto CONFIRM
:LOCK
ren "Private" "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%==yourpassword goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" "Private"
echo Folder unlocked
goto End
:FAIL
echo Incorrect password
goto end
:MDLOCKER
md Private
echo Private folder created
goto End
:End

🛡️ 2. Replace yourpassword with your actual password

Pick something secure but memorable.

💾 3. Save the File as a Batch Script

• Click File → Save As
• Set file name: locker.bat
• Choose All Files under file type
• Save it in the folder where you want the protected folder to appear

---

🧪 How It Works

• Run locker.bat → it creates a folder called Private
• Drop your files inside it
• Run locker.bat again → press Y to lock it
• The folder disappears (hidden + disguised as Control Panel)
• Run locker.bat again → enter password to unlock it

🧠 Jake Says: You’ll only see the folder again after you enter the correct password.

⚠️ What to Know

• This isn’t encryption — it just hides the folder in a clever way.
• Anyone who opens the .bat file in Notepad can see the password unless you obfuscate it.
• Use it for casual privacy—not for tax records, sensitive client files, etc.

---

💡 Bonus: Add a Layer of Obscurity

• Rename locker.bat to something boring like sysconfig.bat
• Store it in a subfolder
• Disable file extensions visibility so others can’t tell it’s a batch file
  (View → Hide extensions for known file types)

📌 TL;DR – Lock a Folder in 60 Seconds

🧢 Jake’s Final Word

Sometimes you don’t need fancy software—just a clever little trick.
This one’s been around for years, and it still works like a charm.
