title: How do I verify the existence of a flat file in an SSIS package?
body: <p>I have a tab delimited file on a shared path.  I've setup that flat file as a connection in an SSIS package.  I'd like my package to verify the existence of the file before I try to do transformations and import it into a database table.  I'm new at this, and I'm replacing a script that checks the existence of the file by hard-coding the path into a script (which I'd like to avoid).  </p>
  
  <p>Is there a way to reference the path from the connection from within a script or some other method I'm unaware of?</p>
