Ediff often fails on compressed files. Take the following steps to reproduce it:
$ echo "foo" | gzip -c > foo.gz $ echo "bar" | gzip -c > bar.gz $ emacs -Q --eval '(ediff-files "foo.gz" "bar.gz")' Emacs will beep and display the buffer "*ediff-errors*" containing a line with Binary files /tmp/foo.gz and /tmp/bar.gz differ (or whatever `diff' outputs). Here is the complete "*Messages*" buffer: Loading help-fns...done Loading mwheel...done (emacs -Q --eval (ediff-files "foo.gz" "bar.gz")) Loading tool-bar...done Loading image...done For information about the GNU Project and its goals, type C-h C-p.
