title: Use external file or resource?
body: <p>I am writing a C# application that uses a long "hard-coded" string.</p>
  
  <p>For maintainability reasons I have decided to put this string in an external text file and load it. Is this a good idea? The extra I/O does not seem big in this case.</p>
  
  <p>I realize that I also have an option to embed this file as a .resx resource. Is this a better idea? The file will never need to be localized.</p>
