C. Copy AdventureWorks2008_Data.mdf and AdventureWorks2008_Log.ldf to
‘C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\’
If you see a folder called ‘Documents’ in the downloaded files set, then copy this folder also to ‘C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\’
