title: Indy FTP TransferType
body: <p>I'm using the IdFTP (Indy 10) component to download some files (zip and txt) from a remote location. Before getting each file I set the TransferType to binary.</p>
  
  <pre><code>IdFTP.TransferType := ftBinary;
  IdFTP.Get(ASource, ADest, AOverwrite);
  </code></pre>
  
  <p>I expect that both text and binary files can be downloaded using the binary mode. However it looks like text files contents is messed up while zip files are downloaded correctly. If I set the TransferType to ASCII for text files it works as expected. How can I detect which TransferType to set for a given file? Is there a common denominator or auto setting?</p>
