How to Lock folder without any software with password

Step 1: Open Notepad
Step 2: Add Code to Document
            Now just copy the text below and paste it into your document.
@ECHO OFF
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Private goto MDPrivate
:CONFIRM
echo Are you sure to lock this 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 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 Your Secure Folder
set/p "pass=>"
if NOT %pass%== wonderhowtogoto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDPrivate
md Private
echo Private created successfully
goto End
:End

Step 3: Edit Folder Name & Password

With the text pasted in, you can adjust the locked folder's name, as well as the password used to unlock it. The default folder name is "Private" and the default password is "wonderhowto."

Step 4: Save Batch File

Now save the file as whatever name you'd like, but make sure the name ends in ".bat" and that you select "All files" in the drop-down box when saving. Also, if you opened Notepad directly rather than using the right-click, be sure to adjust you save location accordingly.

Once saved, your file should look like this in the folder you choose:

Step 5: Create Folder

Now double-click on the batch file you just created (or select and hit Enter). You'll notice a new folder comes up.

At this point, you can start adding files to this folder. Don't worry, you can always add to remove files from it later.

Step 6: Lock the Folder

Once you're ready to lock the folder, simply double-click on the batch file (or select and hit Enter), then choose 'y' on the window that pops up and hit Enter.

You'll notice that your folder has now disappeared.

Step 7: Access Your Hidden & Locked Folder

Now whenever you need access to your folder, just double-click on the batch file, input your password and hit Enter.

To re-lock (and hide) the folder, just hit the batch file again. And remember, you can name the batch file and folder whatever you like, you feel free to make sure of this trick in multiple locations on your Windows machine.
