Locking Folder Without Using Any Software

This is just a trick to make the characteristic of your folder locked. Not really "locked" but "like locked". What I mean that this is not really locking your folder instead it is just a trick that the status of your folder looks like it is locked because this cannot be opened easily. This is makes your folder inaccessible.
The trick is to make your folder become a special file by adding extensions on it. This makes your folder not accessible.

Here's the step how to lock your folder without having any software:

1. Create a new folder or if you if you have an existing folder already then you can use it.
2. Add this code right after your folder name

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

   For example: "FolderName.{21EC2020-3AEA-1069-A2DD-08002B30309D}" and you'll be amazed with the result if the this is your first time doing it. The icon of your folder should changed you did it right.
   

With this extension, double clicking your folder will redirect you not directly to the contents of the folder.

Note: To access your folder just remove the extension you've added earlier.

and that was Locking Folder Without Using Any Software
and that was Making you Folder Not Accessible for Some who don't know this.

That's it.
