The above code would automatically list all the logical names of database files and the physical path information for those files. To retrieve this information, I used a built-in class, “MSSQL_DatabaseFile” available in the “rootMicrosoftSQLServer” namespace.

The “for” loop I used in the above code iterates for every database file in the SQL Server database and finally retrieves only the properties of that file.
