Step 1: Enter cmd at runtime, press enter, and open the command line window.

Step 2: in the command line window, switch to the hard disk partition where you want to create the folder, such as drive D.

Step 3: Enter MD123 ... \ \ Enter, and note that there are two decimal points after the folder name.

Ok, ok, let's see if there is a folder named 123. It's under your hard drive. You can neither enter nor delete! Try it if you don't believe me _

So, what should I do if I want to delete or enter this folder? It's also very simple.

If you want to delete it, please enter rd123 ... \ \ in the command line window to delete it. Of course, before deleting it, please make sure that all the files in it are unnecessary and don't delete them wrongly, hehe.

If you want to enter, enter start d: \ 123...\ to open this folder in the command line window (note that it must be the absolute path of the folder, otherwise it cannot be opened), and you can put in any information you don't want others to see!
