How To Make an Undeletable and Unrenamable Folder

Here is a trick with which you can create an undeletable and unrenamable 

folder using command prompt. If you create such a folder, any other person 

cannot delete the folder and cannot rename the folder. However it is to be 

noted that if you keep and files inside that particular folder, then those files 

can be deleted. In other words this trick is useless if you are trying to protect 

your personal data from outsiders. The FOLDER however remains undeletable 

and unrenamable. To learn how to create a password protected folder without 

any software, you can check out my other article here:

The folders that you create have to be named with certain reserved words of 

windows. Therefore you are not at free will to give any name because that 

will make the folder an ordinary one and not undeletable and unrenamable. 

The folder becomes undeletable and unrenamable because it does not 

actually exist. Try creating a new folder with its name as any of the 

following: con, aux, lpt1, lpt2, lpt3 up to lpt9. You cannot do so. This is 

because these are reserved words for Windows. However if we use cmd 

(command prompt) to create new directories with these reserved words, a 

folder is created which becomes undeletable and unrenamable.

So let’s get started. First of all open cmd (command prompt).To open cmd 

you can click on Start>Run. Type in cmd and press Enter. Cmd will open up.

1. Type in a drive other than one in which windows is installed. Example – 

Type in F: and hit enter.

2.Type in md con\ and press Enter(you can use any other reserved word 

except con) (md = make directory)

3. Open the drive in which you created the folder and you will find that the 

folder is undeletable and unrenamable.

To delete the folder, open cmd, type in the drive and hit enter, type in rd 

con\. The folder will be removed. (rd = remove directory)
