What do you mean exactly?

I'm a convicted user of EmacsW32 when on Windows since a long
time. So, I could effectively (now that I know about it) easily
find your functions:

--8<---------------cut here---------------start------------->8---
(defun w32shell-explorer-file (file)
  "Open Windows Explorer with file FILE selected."
  (interactive "fFile to focus in Explorer: ")
  (let ((full-file (expand-file-name file)))
    (setq full-file (replace-regexp-in-string "/" "\\" full-file t t))
    (w32-shell-execute nil (concat (getenv "SystemRoot") "\\explorer.exe")
                       (concat "/n,/select," full-file))))

(defun w32shell-explorer-current-file ()
  "Open Windows Explorer with current file selected."
  (interactive)
  (if buffer-file-name
      (w32shell-explorer-file buffer-file-name)
    (message "Buffer has no file name")))

(defun w32shell-explorer-old (dir)
  "Open Windows Explorer in directory DIR.
For some reason with this function Explorer does not get
focus. Use the new version instead."
  (interactive "DStart in directory: ")
  (setq dir (expand-file-name dir))
  (w32-shell-execute nil dir))

(defun w32shell-explorer (dir)
  "Open Windows Explorer in directory DIR."
  (interactive "DStart in directory: ")
  (setq dir (expand-file-name dir))
  ;;(setq dir (directory-file-name dir))
  (message "dir=%s" dir) (sit-for 2)
  (w32-shell-execute
   "explore" ;;nil
   "" ;(concat (getenv "SystemRoot") "\\explorer.exe")
   (concat "/n," dir)
   ))

(defun w32shell-explorer-here ()
  "Open Windows Explorer in current directory."
  (interactive)
  (w32shell-explorer default-directory))
--8<---------------cut here---------------end--------------->8---

These look great, but the problem is I'd like to be able to use
the described functionality both under Ubuntu and Windows...

Best regards,
  Seb
