How to make new line in mathematica file output?

Question

I know that new line is classically made by "\n".

I want to make a string with lines of data and then export it into a file:

outString = StringJoin["First Line \nSecond Line"]
Put[outString, NotebookDirectory[] <> "testOut.txt"]

The first line, make a decent output in the Mathematica itself:

"First Line 
Second Line"

But in the testOut.txt file , it is :

"First Line \nSecond Line"

Note that it even includes the quotation marks and both in the same line ! What is the solution for that ?

Put[OutputForm[outString], "testOut.txt"]

enter image description here

compare with

Put[outString, "testOut0.txt"]

Alternatively, you can use Export:

Export["testOut2.txt", outString]
(* or Export["testOut2.txt", outString, "Text"] *)

or, WriteString (thanks: Mr.Wizard)

strm = OpenWrite["testOut2.txt"];
WriteString[strm, outString]
Close[strm]

to get the same result:
