title: Is there a limit to entries in a Dictionary<>?
body: <p>I have about 3000 different files I need to organize, and retrieve at different times during the game. </p>
  
  <p>I created my own struct of variables.
  I was thinking about creating a "Dictionary "
  at the beginning of my application, and simply loading all my files before the game starts. </p>
  
  <p>I'm wondering about performance: will a dictionary with this many entries cause my application to be slow?
  Would a large dictionary make "TryGetValue" and "ContainsKey" run slower?</p>
  
  <p>thanks for the advice!</p>
