Thanks everyone! The problem was solved!
I wanted it for this:
(defun open-this-folder ()
"Opens current buffer folder with explorer"
(interactive)
(open-folder default-directory))
(defun open-folder (folder)
"Opens a folder with explorer (winxp only)"
(interactive)
(shell-command
(concat "explorer " (replace-regexp-in-string "/" "\\\\\\\\"
folder)))
(message (concat "Opening folder: " folder)))
