title: How do I edit SSIS package files?
body: <p>I have a DTSX file in a project I'm taking over. I have Visual Studio 2005 Pro, but it just opens it as an XML file. SQL Server Management Studio 2005 does the same. </p>
  
  <p>I've seen people opening these files in some workflow-esque format; Business Intelligence Development Studio comes to mind. </p>
  
  <p>Is this part of Visual Studio or SQL? Does it have to be purchased seperately? Can I open this file in a more useful way with the tools I have?</p>
