Find.find or Dir[**/*] with spaces in filenames?

Friends-

  I have a bunch of automation built using ruby and highline(thanks James and Greg!!!) set up for processing text and image files for the classified and obituaries at the newspaper I work for. But I am trying to make these processes as stable as possible and I am running into issues with image names with spaces in them.

  We have instated a policy that states logos or obit images can only be named with lowercase letters, underscores and numbers and no spaces. but inevitably, images sneak through the system with spaces in the names. I am grabbing these images from a directory structure recursively and resizing and converting them with imagemagick which works great. But when there is an image with spaces in the name it breaks my scripts.

  Here is a small example of what I am doing. Is there a way to properly quote file or directory names with spaces in them using Find.find or Dir[**/(] to recurse through a dir tree and grab appropriate files?

#This is part of a larger class so its just an example of the dir recursing.
   def process(dir)
     @count_conv = 0
     print "converting..."
     Find.find(dir) do |file|
      if file =~ /\.eps$/
         @log_file << file + "\n"
         unless test(?d, file)
           if too_big?(file)
             convert(file, "-resize #{@scale}x#{@scale}")
             puts "Converted to #{@scale}x#{@scale} #{file}..."
           else
             convert(file, '')
      puts "Converted to #{@scale}x#{@scale} #{file}..."
           end
           @count_conv += 1
         end
       end
     end
     @log_file << "\n\n#{@count_conv} logos were converted to correctly sized gifs.\n\n\n"
   end

  So is there another library or option I am missing that will allow something like this to work with directories or files with spaces in the names? I would like to be able to do a sub on the names to replace spaces with underscores.

Thanks in advanced-
