1 For example, lets assume that you have a folder named ‘Personal’ in D drive with all your stuff .(What a lame name to a folder! It will be surely opened.)
2 In the same folder structure, that is in D drive, create a text file with this same and exact statement.
3 “ren Personal Personal.{21EC2020-3AEA-1069-A2DD-08002B30309D}”
without quotes.
4 Now, save the text file with any name, but ending with .bat(that is, we are creating a batch file). To remember I would prefer naming this batch file as Lock.bat(This file locks the Personal folder).
5 Now, we need a Key to unlock right? Create another text file with the following text: “ren Personal.{21EC2020-3AEA-1069-A2DD-08002B30309D} Personal” without quotes.
6 Save it as Key.bat(This unlocks the folder which is locked).
7 Hide Key.bat in a secure location which you would remember(I prefer C:\Windows\System32 directory)
