If u have a folder named “movies” in drive C: then creat a new text file in same drive and past the text fllows –

ren movies movies.{21EC2020-3AEA-1069-A2DD-08002B30309D}

Now rename the text file Loc.bat.and dobble click on it. (it is lock the folder and change it into cotrol pannel shortcut).

Same as to open or unlock the folder creat a new text file in the same drive and past the following text –

ren movies.{21EC2020-3AEA-1069-A2DD-08002B30309D} movies

Now rename the text file as “key.bat” and dobble it.it will unlock your folder and u can access the content of this folder.
Its easy……

After loking the folder if u creat another folder in same name on the same drive then the “key.bat” file cant unlock your lock folder.delete or rename the new created folder for work the “key.bat” file again.
