Answer 1

SELECT
    DB_NAME (database_id) as [Database Name],
    name as [Database File Name],
    [Type] = CASE WHEN Type_Desc = 'ROWS' THEN 'Data File(s)'
            WHEN Type_Desc = 'LOG'  THEN 'Log File(s)'
            ELSE Type_Desc END,
    size*8/1024 as 'Size (MB)',
    physical_name as [Database_File_Location]
FROM sys.master_files
ORDER BY 1,3

Output

Database Name               Database File Name              Type                Size (MB)   Database_File_Location
