Sometimes, when trying to connect to a database or attach an MDF file, you might have trouble finding the file.In the upcoming section, we’ll discuss different ways to locate MDF files.

You may also use a third-party application to access or find MDF location in SQL Server.MDF File Location in SQL ServerFollowing are the two ways to determine location of an MDF file:Check the Default Location of MDF FileThe default location of the MDF file depends on the SQL Server version (2019, 2017, 2016, and earlier) you’re using.

All versions of SQL are located in the same directory named “Microsoft SQL Server.”SQL Server 2014C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\xxx.mdfSQL Server 2016C:\Program Files\Microsoft SQL Server\MSSQL13.MSSQLSERVER\MSSQL\DATA\xxx.mdf     SQL Server 2017C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\DATA\xxx.mdf     SQL Server 2019C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\DATA\xxx.mdf     Depending on your suitable version of SQL Server, you can easily locate your MDF file and navigate to it.

All files that are common to be used by the servers or systems can be installed inside a folder named “nnn.” The exact file location is folder:\Program Files\Microsoft SQL Server\nnn\Use T-SQL Query You can get the list of log and data files in the SQL server by running the following T-SQL query:USE master;SELECTname ‘Logical Name of File,’physical_name ‘File Location’FROM sys.master_files; If you need to find database files for a specific database, execute this T-SQL code:USE database_name;SELECTname ‘Logical Name of File,’physical_name ‘File Location’FROM sys.master_files; In this code, replace ‘database_name’ with the name of your db.

In that case, using a SQL repair tool may help.
