I think that DareDevil wants to know about Terabit's DataPak support in BlitzView. He wants to know what is included and how the files are extracted. I'm not a BlitzView user so I'm not sure about how they interact but you can get Terabit's DataPak from : http://www.blitz3d.co.uk/index.php4?page=download&download_no=20
It should come with some documentation explaining its use and what you need to include in your project.
