Undeletable & Unrenamable Folder

How To Create Undeletable And Unrenamable Folders ?

• Go to Start and then Click on RunType cmd & hit enter (To open Command Prompt ).
• Remember you cannot create Undeletable & unrenamable folder in your root directory (i.e. where the windows is installed) That means you can't make this kind of folder in C: drive if you installed windows on C:
• Type D: or E: and hit enter
• Type md con\ and hit enter (md - make directory)
• You may use other words such as aux, lpt1 , lpt2, lpt3 up to lpt9 instead of con in above step.
• Open that directory, you will see the folder created of name con.
• Try to delete that folder or rename that folder windows will show the error message.
