How to Lock Folder in windows 7 without using any 3rd party software

This tutorial will guide you through the steps required to create a locked folder in Windows 7 – without installing any additional 3rd party software.While the steps below will guide you in creating a hidden and password protected folder, this method is not 100% secure. It will deter the average computer user enough, but an advanced user will be able to access the contents of this folder. 

1. Create a new folder and name it whatever you would like.

1. Open the folder, right-click on a blank area in it, then select New -> Text Document from the pop-up menu.

1. Open the text file you just created by double-clicking it and copy/paste in the following text:

cls@ECHO OFFtitle Folder Privateif EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCKif NOT EXIST Private goto MDLOCKER:CONFIRMecho Are you sure you want to lock the folder(Y/N)set/p "cho=>"if %cho%==Y goto LOCKif %cho%==y goto LOCKif %cho%==n goto ENDif %cho%==N goto ENDecho Invalid choice.goto CONFIRM:LOCKren Private "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"echo Folder lockedgoto End:UNLOCKecho Enter password to unlock folderset/p "pass=>"if NOT %pass%== PASSWORD_GOES_HERE goto FAILattrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Privateecho Folder Unlocked successfullygoto End:FAILecho Invalid passwordgoto end:MDLOCKERmd Privateecho Private created successfullygoto End:End

1. In the above code, replace the key PASSWORD_GOES_HERE with the password you want to use to unlock the folder. For example if you want the password to be 123456, the line should look like:

if NOT %pass%== 123456 goto FAIL

1. Save your new file in the .bat format with the complete file name being locker.bat. To do this, make sure to change the Save as type: to All Files (*.*).

1. In the folder you created back in Step #1, double click the locker.bat file and there will now be a new folder named Private where you can put anything you want.

1. Upon exiting, double click the locker.bat file again. It will prompt you to answer whether you want to lock your folder or not. Press Y and the private folder will disappear.

1. In order to retrieve the Private folder, all you have to do is double click the locker.bat file and enter the password which you set in Step #4 and the folder will appear again for you to access.
