Make Undeletable, Unrenamable Folders (Cmd)

Click on Start.
Click on Run. Type in “cmd” without quotes.

In the Command Prompt Window that opens, type the name of the drive you wish to create your folder in the format <drive-name>: 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).

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.

* Note – 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.
