As most of us know that MDF (also known as Master Database File) is the primary database file of Microsoft SQL Server used to store all the crucial data of the database. The MDF file stores all the data in relational databases that include Tables, Rows, Columns, Fields, Indexes, etc.

Although it is a primary database file of SQL Server, most users think that it can only be opened in SQL Server but are not aware of the exact procedure to open an MDF file. Thus, we are here to provide you with a comprehensive guide for the same.

Additionally, we also get queries about how to open MDF files when they don’t have the SQL Server environment. So, we will also discuss a free solution for those users as well.

If you don’t know the default location of your SQL MDF file, then you can find the files in the following locations depending on the SQL Server version that you are using.

Default Location of MDF Files in Different SQL Servers

How to Open SQL MDF File Using SQL Server Management Studio

When we try to open an MDF file in SQL Server, then we don’t actually open the file. The actual process is known as attaching the MDF file with the SQL Server. Once the MDF file is attached, the database objects can be seen in the object explorer of SQL Server Management Studio (SSMS).

  • 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 of 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.

Moreover, if any user has a damaged MDF file and wants to open it in SQL Server, then also the above procedure will fail to open it.

So, users who want to open their MDF files without any SQL server or have a damaged MDF file can go for the advanced solution discussed below.
