1.  Open Notepad.

    2.  Copy and paste the exact code given below:

    cls

    @ECHO OFF

    title computer-tricks-corner.blogspot.com

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

    if %cho%==Y goto LOCK

    if %cho%==y goto LOCK

    ren MyFolder "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%== computer-tricks-corner.blogspot.com goto FAIL

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

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

    echo Folder Unlocked successfully

    goto End

    :FAIL

    echo Invalid password

    goto end

    :MDMyFolder

    md MyFolder

    echo MyFolder created successfully

    goto End

    :End

    3.  Click on the File Menu. Click on Save As.

    4.  Select All Types (or all files) in the Save As Type dropdown menu. Save the file as *.bat or Locker.bat

After creating the file, double click on the Saved file. A new folder will be created. Enter your data in the folder. Again, double click on the batch file. Type Y and press Enter. The folder will be hidden from view.

To re-view your folder, double click on the saved batch file. Enter password as

" computer-tricks-corner.blogspot.com " without quotes ("") and press Enter key. This is also the default password. Your folder will be visible again.

To change the default password, edit the part of the code given in blue and enter your own password.

The overall usability of this trick can be improved by deleting the batch file after hiding your folder and re-creating it when you wish to access your folder again.

Note : This works on Windows 7, Windows XP and Vista. First try this on useless data to be sure and then only hide your personal data.
