Does your situation match the case "If the files that you want to process are sequentially numbered", or does your situation match the case "f you want to process all the files whose name matches a pattern in a directory" ? When you visited that link I posted about How can I process a sequence of files, do the three sample blocks of code there show up empty?

Maybe, it would be better to turn the question around and ask Chris, which step is causing him problem:
  1. read the scaling file
  2. get or create the list of files to process
  3. iterate over each file and
  4. read the file
  5. multiply by the scaling file
  6. write to a new file
