How To Create Undeletable & Unrenamable Folder in Windows

Suppose, we have a folder containing some hundred very important files and by accident someone deletes it permanently (even from the recycle bin), either by mistake or to knock you into trouble. What happens? Well, you are just doomed, that’s all. But don’t worry, because there happens to be a so called inner “trick” with Windows by which we can create an ‘undeletable’ and ‘unrenamable’ folder inside which we can place our important documents. Through this protection, you can really gain the security for your private folder.  It’s a bit old one but ‘protection from deletion’, hell yeah!!
Actually, the matter in this undeletable folder is the use of keywords or ‘reserved words’. Try to make a new folder in Windows & give it names like con, aux, lpt1, lpt2, lpt3 up to lpt9.
You won’t be allowed to create folder with above mentioned names, because they happen to be the reserved words in windows.
Steps to be followed :
How To Create Undeletable And Unrenamable Folders ?

1. Go to Start Menu=>RUN
2. Type cmd& press Enter (To open Command Prompt ).
3.  If you don’t know what is Command Prompt,
   Note:  You cannot make this kind of a folder in C: drive if you installed windows on C: , so try  it out on other drives.

4. Type D: or E: or F: (The drive you like except C:)and press Enter.
   
   
   
5. Type md \lpt1\\and hit Enter (md implies make directory). You may also use other words such as aux, con, lpt2, lpt3 up to lpt9instead of lpt1.
6. Open that folder which you chose , and now you will be able to see the folder named lpt1.

Now, try to delete that folder or rename that folder, either ways Windows will show an error message. (Like the one shown below)

How to Delete that Folder ?
It is not possible to delete that folder manually, but it is possible to delete this folder by another way mentioned below.

1. Open Command Prompt (cmd).
2. Type the name of the folder in which you created it ( if u created this type of folder in E: drive, type E:) & press enter
3. Typerd \lpt1\\ (rd implies remove directory)

Now, open that drive and you can see that the folder has disappeared from there, because it is removed.
