I worked on my Database Inventory script a bit and am releasing an enhanced version of the original.
When run in the Master database, the script displays a list of all user databases located in the specified sql named instance, along with file name, file type, file path and file size columns.

USE [Master]
GO
SELECT
(SELECT 'file_type' =
CASE
WHEN sysaltfiles.groupid <> 0 THEN 'data'
WHEN sysaltfiles.groupid = 0 THEN 'log'
END) AS 'file_type'
, sysdatabases.name AS 'db_name'
, sysaltfiles.name AS 'logical_file_name'
, sysaltfiles.filename AS 'physical_file_name'
, (sysaltfiles.size * 8 / 1024) AS 'file_size(MB)' -- file size in MB
FROM
dbo.sysdatabases
JOIN
dbo.sysaltfiles ON
(dbo.sysdatabases.dbid=dbo.sysaltfiles.dbid)
WHERE
sysdatabases.dbid NOT IN ('1','2','3','4')
ORDER BY
dbo.sysdatabases.name
Hope this helps!
