How can I open an .MDF file in SQL Server?

Let us suppose as if someone is trying to give their formulated SQL server database because they want you to manage their SQL Server Database and even troubleshoot errors if anything if available, moreover you can also gain required information from it. Thus they hand over to you the .MDF file and .LDF file and inform you that you require SQL server 2008 R2 in order to unlock them. Therefore for the sake gaining access, you install SQL Server 2008 R2 Express assuming it to free from your concern. When you open SQL Server Management Studio (SSMS), and when you attempt to unlock the .MDF file.

The resolution is:

.MDF files are known to be SQL Server database files and .LDF files are the log files that are connected. But still you fail to “open” them. As an alternative you have to get “attached” to them. Once you put together, you will observe that the database in the object explorer of SSMS.
