title: How to properly use File.Exists in windows application
body: <p>I have a windows application with an "images" folder. I need to check if an image exists, which it will, during runtime. The below code is what I have but it always returns false.</p>
  
  <pre><code> if ( File.Exists("images/" + item.tool_image) )
          {
              Image img;
              img = Image.FromFile("images/" + item.tool_image);
              titem.Image = img;
          }
  </code></pre>
