to delete dir, you need to set a built-in var.

Q: How to delete or copy a entire directory

A: Type “Alt+x customize-variable” then “dired-recursive-deletes”, then click on the Value Menu to make a choice. Then, click “Save for Future Sessions”, then “Finish”. Do the same with variable “dired-recursive-copies”.

;; allow dired to be able to delete or copy a whole dir.
(setq dired-recursive-copies (quote always))
(setq dired-recursive-deletes (quote top))
;; “always” means no asking.
;; “top” means ask once (top = top dir).
;; any other symbol means ask for each dir or subdir.

if you are running emacs 23, deleting trash is already part of it.

Deleting files in emacs can now be set so that they move to the OS's trash.

; deleting files goes to OS's trash can
(setq delete-by-moving-to-trash t) ; “t” for true, “nil” for false

However, this feature has a few problems. When this is on, your system trash will be filled with tens or hundreds of emacs temp files, such as those “#autosave#” files, “backup~” files, “.emacs.desktop”, “emacs00164”, “server”, etc. Also, when deleting a directory from dired, your system trash will end up with each individual files, instead of just a folder. If the folder has few hundred files, the process will be super slow. This happens at least on Windows emacs.
