But you can now create such folder with a simple trick.

Step 1: Open Command Prompt, then Type

mkdir \\.\E:\CON

The red coloured text is the folder name here and the Blue Colour, Drive alphabet. Then Verify that folder by

dir \\.\E:\CON

Now that folder is Created. In this way you can create all the file names mentioned above. To delete that folder, type,
