How to lock a folder in Windows without using any 3rd party software

Every one wants security in his/her life. We use different means to secure our self. Same as in case of computer we need security for our files that we don’t want any one to use . So how to lock a folder in our computer without any 3rd party program?

• Create an elevated command prompt, if not done yet
• Create two batch files:

REM This batch-file prevents to use data in <foldername> folder
@ECHO OFF
REN <foldername> <foldername>.{20d04fe0-3aea-1069-a2d8-08002b30309d}

After executing the above command the <foldername> folder will look like "My Computer" icon and will act like "My Computer" of Microsoft Windows operating system, means if you now click on <foldername> then "My Computer" will open instead of your <foldername> folder.

REM This batch-file allows to use data in <foldername> folder previously prevented
@ECHO OFF
REN <foldername>.{20d04fe0-3aea-1069-a2d8-08002b30309d} <foldername>

This reconverts <foldername> folder to its original state.

That's something like putting your money under the mattress. Good, until someone takes a peek, then it's all gone. Windows has reasonably good file encryption built in. If the contents needs to be locked its a far better way. Just remember to disable administrative recovery.

Correct. But if your encryption certificate and key are lost or damaged and you don't have a backup, you won't be able to use the files that you have encrypted.

Why not just make your folder Invisible ????????? works for me and easy too do , realy depends on how sensitive your data is ????? If its super high Sensitive for your eyes only THEN DONT LEAVE IT ON A LOCAL MACHINE , store it offline somewhere.

I have been using Folder lock all along I guess there is also another way to lock them without the use of third party software. I think it is a great method for every tech savvy person must know. They need to have more than one way to make something happen.

That will work fine for "Joe Average" but anyone with half an idea that something is to be found will be able to bypass that just by booting from a live CD running an alternate OS.
