title: How many bytes does a file called 'file.txt' with the text "test" take?
body: <p>I have a file on my my desktop called 'file.txt' and it contains the text "test".
  When i right click the file go to properties, and view the size it says 4 bytes.
  This makes sense because 4 characters = 4 bytes, but the file is called file.txt so this does take some space right? 
  It only says the file takes 4 bytes and nothing more. 
  I have tried searching on the web but i could not find a answer to this question.
  So how many bytes does a file called 'file.txt' with the text "test" actually take?</p>
