Locking folders without using encryption softwares

I know you really wanna hide your real data from strangers, family, friends, or any. This is a very simple process which will change your imagination into real. There are many ready-made softwares also, but would you like to spend your money on that, if you are getting free knowledge from here.

Create a new folder, rename it Shadab.

Go to its properties and change its icon to blank/invisible one.

Now create a file in the same drive and write it in:                                                                                 

ren Shadab Shadab.{b5946137-7b9f-4925-af80-51abd60b20d5} 
Save it as for example Encrypt.bat

Again create a file int the same drive and write:                                                                 

ren Shadab.{b5946137-7b9f-4925-af80-51abd60b20d5} Shadab  

Save this as decrypt.bat.

You are done use Encrypt.bat to lock the folder and Decrypt.bat to un-lock it.                    

Congrats..Now you have created an inaccessible folder.
