Using Thorsten's suggestion

--8<---------------cut here---------------start------------->8---
(setq org-link-abbrev-alist
'(("foo" . "file:/path/to/%(foobar).txt")))

(defun foobar (x)
  (replace-regexp-in-string "[[:space:]]" "_" x))
--8<---------------cut here---------------end--------------->8---

will turn

[[foo:foo bar  loo]]

to

[[file:/path/to/foo_bar__loo.txt]]

when you click on it.
