Find Physical file location for all the databases in SQL Server


Very often DBAs need to find the location of the physical file (MDF, LDF & NDF) of a database. Simply we can obtain the output by executing the below query. Run the script to get the SQL Server database file location for all the databases for a particular instance.

Retrieving Database File Details Using T-SQL

In SQL Server, obtaining detailed information about your databases and their associated files can be crucial for effective management and maintenance. This blog post will guide you through a T-SQL script that fetches comprehensive details about the database files on your server. This script, authored by Soyeluddin Biswas, leverages system views and dynamic management views to provide valuable insights into the file size, location, and usage.

Script to find the physical file location

-- T-SQL Author: Soyeluddin Biswas
-- Website:
-- Created Date: 25 September 2019

-- Declare and set the server name
SET @ServerName = CAST(SERVERPROPERTY('MachineName') AS NVARCHAR(128))

-- Retrieve the database file details
  @ServerName AS [Server Name], -- Server name AS [Database Name], -- Database name
  d.database_id AS [Database ID], -- Database ID AS [Physical File Type], -- Type of the physical file
  f.physical_name AS [Physical File Location], -- Location of the physical file
  f.state_desc AS [Online Status], -- Online status of the file	
  f.size * 8.00 * 1024.00 AS [Size In Bytes], -- Size of the file in bytes	
  CAST((f.size * 8.00 * 1024.00) / 1048576.00 AS NUMERIC(18,2)) AS [Size In MB], -- Size of the file in megabytes	
  CAST((f.size * 8.00 * 1024.00) / 1073741824.00 AS NUMERIC(18,2)) AS [Size In GB], -- Size of the file in gigabytes	
  CAST((f.size * 8.00 * 1024.00) / 1099511627776.00 AS NUMERIC(18,2)) AS [Size In TB], -- Size of the file in terabytes	
  CAST(CAST(v.total_bytes - v.available_bytes AS FLOAT) / CAST(v.total_bytes AS FLOAT) * 100 AS NUMERIC(18,2)) AS [Used Disk Percent] -- Percentage of disk space used by the file
  sys.master_files f
  INNER JOIN sys.databases d ON d.database_id = f.database_id	
  CROSS APPLY sys.dm_os_volume_stats(f.database_id, f.file_id) v
  --d.database_id -- Sort by database ID
  [Size In GB] DESC -- Sort by size in gigabytes in descending order
