Subject: "puts"ing an array

Hi,
In the "pickaxe" book I see how to use a "puts" to populate a file with
data. I try the same thing, and, it works, but, it's listing the data as
an array. How can I get separate lines for each item in the array?
Thanks,
Peter

In the book:
 File.open("output.txt", "w") do |file|
 file.puts "Hello"
 file.puts "1 + 2 = #{1+2}"
 end
 # Now read the file in and print its contents to STDOUT
 puts File.read("output.txt")
produces:
 Hello
 1 + 2 = 3

My script:
 Dir.chdir("L:/png/69000")
 files = Dir.glob("*.png")
 File.open("F:/workflows/graphics/receipts/pngfiles.txt", "w") do |file|
  file.puts "#{files}"
 end
produces:
 69116.png69251.png69391.pngAZ69080.pngAZ69982.pngcx69362.pngcx69363.png
