Hello Friend's,
Am going to share a triCk with you all which will lock your private/data folders in easy 5 steps :)
so let's start

1) First of all make a folder on the desktop and name it as 'Private'.

2) Now,open notepad and paste this in notepad 'ren Private Private.{21EC2020-3AEA-1069-A2DD-   08002B30309D}' (Without Quotes) and save it as 'lock.bat' (Important Notice .bat extension is must) on your desktop.

3) Now,again open notepad and paste this in notepad 'ren Private.{21EC2020-3AEA-1069-A2DD-08002B30309D} Private' and save it as 'key.bat' on your desktop.

4) Now,Double click 'lock.bat' file to lock your folder (Namely "Private") and after that double click your folder you will notice that instead of opening your folder it will prompt you to the "Control Panel".

5) Now,For opening your folder again double click 'key.bat' file and after that double click your folder and voila your folder (containing private data) will be open without any damage of data.

Useful Tip : Lock your folder and hide the key.bat somewhere else on your hard disk,Whenever you want to open your folder just paste the key.bat on desktop and open your folder using it.
