Thank you.
For deleting 2-3 files Emacs24 and Emacs25 differs; for deleting
many files they looks pretty similar:

emacs -Q
C-x 2
;; Visit a directory with several hundred of files.
M-: (dired (expand-file-name "lisp" source-directory))
RET
t D no RET
;; In both releases the window displaying *scratch* becames very small.
