title: SSIS flat file location. Local drive vs shared folder on same server
body: <p>I have a flat file stored locally on the same server where SSIS is running.  </p>
  
  <p>When choosing the location of my flat file in the flat file connection manager, I could use the local drive (d:\testfiles\flatfile.txt) or I could use the UNC path (\myserver\flatfileshare\flatfile.txt.)  </p>
  
  <p>Both are pointing at the same file and the package is succesful either way.  Is there a performance reason for why I should choose one over the other? </p>
