title: What's the difference between DragDropEffects.Copy and DragDropEffects.Move?
body: <p>I have looked all over the internet for an answer to this question and I cannot seem to find it.</p>
  
  <p>What's the difference between DragDropEffects.Copy and DragDropEffects.Move?</p>
  
  <p>In my code on the DragEnter I set it to:</p>
  
  <pre><code>private void Canvas_DragEnter(object sender, DragEventArgs e)
      {
          if (e.Data.GetDataPresent(DataFormats.FileDrop))
              e.Effect = DragDropEffects.Move;
      }
  </code></pre>
  
  <p>But if I use</p>
  
  <pre><code>private void Canvas_DragEnter(object sender, DragEventArgs e)
      {
          if (e.Data.GetDataPresent(DataFormats.FileDrop))
              e.Effect = DragDropEffects.Copy;
      }
  </code></pre>
  
  <p>There is no difference in the program.</p>
  
  <p>Could someone please explain the difference? </p>
