For example, I open D:\back

Run del.bat inside it

The batch content is rd /s/q d:\back

And this bat only deletes all files under d:\back, but does not delete the d:\back folder..

How to do it? The premise of deletion is that del.bat must be inside the back folder..

Just like shift+del to delete, the directory is open. Also force delete.

It can be written like this:
cd\
rd /s/q d:\back

What does adding a `cd\` mean? Is it going to the root directory of drive D? Then execute the following command?

"cd\" is to return to the root directory of the current drive no matter where you are
