Would renaming things as you go interfere with File.find or does it
slurp all the file names up before hand?

You could just do the operation as you go:

   Find.find(path) do |file|
     fix(file) if /.eps$/.match(file)   # or whatever
   end

The fact that it's got the path attached shouldn't matter for the
renaming operation, since you're not chdir'ing.
