I think you want something like (defun split-path (path) (split-path-1 path ())) (defun split-path-1 (path accum) (let ((dir (directory-file-name (file-name-directory path))) (name (file-name-nondirectory path))) (if (equal dir path) accum (split-path-1 dir (cons name accum))))) I totally agree that something like that could be built in.
