Dired: only one buffer when input/exit in directory

Question

Windows 10, Emacs 25.1, Dired, Dired+

When , in dired mode, I enter (by press RET) to directory the dired create many buffers. Something like this:

As you can see was crated 4 buffers: Temp, test, test2, test3

But I need the next:

1. Input in directory by press key RET
2. Create always only one buffer when I input in directory and exist/up from directory (by ^)

Answer 1

Use Dired+, and put this in your init file:

(diredp-toggle-find-file-reuse-dir 1)

That makes Dired kill the current Dired buffer when you visit another directory in Dired.
