title: How to add new columns to Flat File conn in SSIS without resetting data types for existing cols
body: <p>SSIS 2005</p>
  
  <p>I have a flat file connection which is the result of a db dump.</p>
  
  <p>New columns have been added to the file and now they need to be added to the connection manager.</p>
  
  <p>There are a lot of columns and not all of them have the default dataypes</p>
  
  <p>How can I make it see the additional columns without doing a full refresh, thereby causing all the datatypes to reset?</p>
