He's creating a file named ".output*.*" and deleting it with the line
you used. He's showing you 2 errors there:
 1) usage of '\' in the string: it's gotta be escaped: "\\"
  NOTE: maybe Ruby uses '/' as a dir. separator even in Win*, you'll
  have to test
 2) File.safe_unlink doesn't accept file globs.

 Use something like (untested)
 
 require 'ftools'
 files = Dir[".\\output\\*.*"]
 files.each { |x| File.safe_unlink x }
