How to Open MDF File in Windows Using SQL Server Management Studio?

When we try to open an MDF file in SQL Server, we don’t actually open the file. The actual process is known as attaching the MDF file to the SQL Server so that SSMS can execute the process & users can cut down the need of MDF file opener. Once the MDF file is attached, the database objects can be seen in the object explorer of SQL Server Management Studio (SSMS) with the Windows operating system.

• Launch SQL Server Management Studio and connect to the SQL Server Instance.
• Once connected, you will see the SQL Server Instance.
• Now go to the Object Explorer >> right click on the Databases >> Attach.
• Click on Add button in the Attach Databases window.
• Following that, locate the MDF file on your system and click on the OK button.
• Click on the OK button again and the database will be attached.

There are the steps to open the MDF file for free on your system. Despite being free, the major limitation of this process is the requirement for the SQL Server environment to open the file. Thus, any user who doesn’t have the Live SQL Server environment cannot implement the aforementioned process.
