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.
I've seen people opening these files in some workflow-esque format; Business Intelligence Development Studio comes to mind.
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?
