How to create an import/Export format file.

• Verify your mdf is accessible via Sql Server Manager  
• Open a command prompt
• bcp DatabaseName.dbo.TableName format nul -fc:\temp\FormatFIle.txt -n -S.\SQLEXPRESS -T
• If the first line in FormatFile.txt contains a 9.0, your running the 2005 version of bcp, otherwise it should be 10.0. On systems installed with both 2005 and 2008, the path environmental variable might require modification. If you want to run the 2008 version of bcp, move "C:\Program Files\Microsoft SQL Server\90\Tools\binn\"  to the end of the path. Restart computer after path change.
