Is C:\Program Files\GnuWin32 in your PATH environment variable? The simplest thing would be to add it, so that you can run diff (and any other GnuWin32 programs you install) via M-! and M-|. Your other option is to set the Emacs ediff-diff-program variable to the absolute path to the diff executable. > Appologies for the level of this question, and thanks in advance, No need to apologize -- this is gnu.emacs.help! -- Kevin Rodgers Denver, Colorado, USA
