How to create such special filename characters (like a small triangle)

In edit, you can output like this: ctrl+backspace key,
In cmd, I don't know.

Thanks to gqtc, is there any expert who knows how to type this symbol in CMD or pure DOS ;).

This character has an ASCII value of 127, which is the (del) character. It cannot be directly typed in cmd. You can hold down ALT in Notepad, then press 127 on the numeric keypad, and then release the ALT key.

Thanks, it turned out to be the (del) character. No wonder I couldn't access the folder in CMD.

Now summarize the establishment of this abnormal directory:
From floors 2 and 4, it is known that this ASCII is 127, which is the (del) character. In CMD, it is impossible to directly use RD to create such a directory. Then, we can create a new batch file with the content:

md \..\

The empty space after \ is obtained by pressing alt+127 on the keyboard

In this way, the directory is successfully created. The dots between \\ and the ASCII itself are added, such as \....\, \......\, etc.

This kind of directory cannot be accessed in CMD
It can only be accessed through running

It's really strange stuff. I tested on a ramdisk virtual NTFS partition. Just after creating it, I couldn't enter. Then I was lazy and dragged a file with the Ctrl key, and it actually went into the directory. Then an unticked directory appeared. Then I could actually delete it. Delete the directory with the dot, EEE, the unticked one then became the one with the dot and the files inside were really deleted. Strange thing.

Create a folder named "a." and "a". Then drag "a" into "a.", and it shows "Cannot XXX.... The file name extension is too long". Open "a." or "a" and see that inside there are "a" and "a" and so on in an infinite loop. The path is "a.\a\a\a\a\.....". Moreover, if you drag a file into it, opening "a." or "a" under Windows will show the same file. It's like mutual mapping. But if you check with cmd, "cd AE216~1 &dir" can find that the files dragged in under Windows don't actually exist, and the files created in that folder using commands can't be seen under Windows (when there are "a." and "a").

Everyone, try to create a folder named after a drive letter
md "c: \\"
When deleting with the mouse --- unable to read the original disk or file

Got it

set pp="122."

md %pp%\

pause

Copy the above code
Of course, it's easy to rename without adding dots
(PS: Actually, it can be established directly under Windows, rename with ctrl+backspace or alt+127)
