Guy-

Thanks, but a follow-up question:

How exactly would I rewrite my file (which happens to be named “dl.rb”) which currently includes just this text:

require ‘ftools’
File.safe_unlink(“.\output*.*”)

Do you think this code should be correct as written? (I don’t
understand your “ruby -rftools -e” text.)

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 }
