As I was trying to install the sample databases for sql server 2008 I downloaded the datafile 'AdventureWorks2008R2_Data' from codeplex.com. However, when I was double clicking the file trying to instiall it an 'Caution' message as below:
You are attempting to open a file of type 'SQL Server Dtaabase Primary Data File (.mdf) These files are used by the operating system and by various programs. Editing or modifying them could damage your system. If you still want to open the file, click Open with. Otherwise, click Cancel.
I was just wondering did I download the correct file? or there's something else I missed?
