Make Undeletable, Unrenamable Folders

Basic Concept
The basic concept behind this trick is the use of Keywords. Keywords are reserved words in any programming language that cannot be used as names of variables. Windows also uses certain keywords in its programming. Some of them are con, aux, lpt1, lpt2, lpt3, lpt4, lpt5, lpt6, lpt7, lpt8 and lpt9.

Trick
So the question arises, how can we make a folder with a keyword as its name? The solution to this problem is included in Windows itself. As we know that Windows has evolved from D.O.S.(Disk Operating System), its commands can be used in Windows. You can use D.O.S. Programming in Windows to create a folder with a keyword as its name using the steps given below:-

1. Click on Start.
2. Click on Run. Type in "cmd" without quotes.
3. In the Command Prompt Window that opens, type the name of the drive you wish to create your folder in the format : and press Enter. e.g. If you wish to create the undeletable folder in D drive, type "D:" without the quotes. Note that the folder cannot be created in the root of C: drive (if C: is your system drive).
4. Type this command- "md con\" or "md lpt1\" without the quotes and press Enter. You can choose any of the keywords given above as the name of your folder.

Now Windows will create an undeletable, unrenamable folder in the drive you entered in Step 3. However, the folder can be renamed to another keyword using Windows Explorer.

Deleting the Folder

Although, it is not possible to manually delete the folder, you can delete the folder by typing "rd con\" or "rd lpt1\" in Step 4 instead of "md con\" or "md lpt1\". 

Windows Compatibility: This works on Windows XP, Windows Vista, Windows 7, Windows 8 and Windows 8.1.

Try it yourself to create one such folder which can neither be deleted nor be renamed.
