that was actually what I had in mind, my mistake.

that works beautifully, thanks! However, there are a few files in one directory 
with no corresponding files in the other directory - they are easy to miss in 
my case (1000+ files). I luckily knew about them so I noticed that 
ediff-directories does not list them - is that by design?

- courtesy of the extremely useful tramp-package (which we use every day for 
editing remote files)?

Warm regards,
