title: How to join two binary files on Windows
body: <p>I created two binary files. I would like to concatenate both of them into one with the second one starting at offset <code>firstFile.Size</code> in the resulting file. I tried using a command in cygwin on Windows. </p>
  
  <p>I entered the following command in cmd </p>
  
  <pre><code>cat file1.bin file2.bin &gt; file3.bin
  </code></pre>
  
  <p>It generates an output file but it is 0 bytes in size. Does anyone know how this is done?</p>
