How to Create a Password Protected Folder without any Extra Software

For example I have a important data in a folder in C drive which I want to lock it.

Open a notepad and paste the below given script in it.

_____________________________________________________________________

cls

@ECHO OFF

title Folder Private

if EXIST "HTG Locker" goto UNLOCK

if NOT EXIST Private goto MDLOCKER

:CONFIRM

echo Are you sure you want to lock the folder(Y/N)

set/p "cho=>"

if %cho%==Y goto LOCK

if %cho%==y goto LOCK

if %cho%==n goto END

if %cho%==N goto END

echo Invalid choice.

goto CONFIRM

:LOCK

ren secure "HTG Locker"

attrib +h +s "HTG Locker"

echo Folder locked

goto End

:UNLOCK

echo Enter password to unlock folder

set/p "pass=>"

if NOT %pass%== iforgot@8 goto FAIL

attrib -h -s "HTG Locker"

ren "HTG Locker" secure

echo Folder Unlocked successfully

goto End

:FAIL

echo Invalid password

goto end

:MDLOCKER

md secure

echo secure created successfully

goto End

:End

3) Then save notepad file as .bat file For example: private.bat in C drive and close it.

4)  Now run your batch file by double clicking on it–the first time you run it, it will create a folder called Secure. This is where you can store all your secret things. When you have finished adding all your stuff to the Secure folder, run locker.bat again.

5) This time you will be asked if you sure that you want to lock the folder, press the “Y” key and hit enter to lock your folder.

6) You will see that your Secure folder quickly disappears.

7). If you run the batch file again, you will prompted for a password.

8) If you enter the same password as you set in the script the Secure folder will reappear if you enter the incorrect password the script will just Terminate.

If You Forget Your Password

Seems like once a week somebody writes in asking how to figure out the password they set. And the answer is really simple: Right-click on the locker.bat file and choose Edit.

Then you can see the password you set in the file.
