Finding datafile sizes for all db on server

There is a command DBCC SQLPERF (logspace) that gives the size and % used for log files for all databases on an instance. Is there an equivalent that does that for the datafiles? Or at least the aggregate of total disk used by all the datafiles in a database?
I am using SQL Server 2008.
I've looked at sys.master_files but that doesn't show the % used or anything that I could see to calculate that.
Yes, I'm looking to see which databases are near hitting autogrow events and which ones are grossly oversized.
Any input is appreciated, and thank you for your time.

I use both of these:

SELECT DB_NAME(database_id) AS DatabaseName,

Name AS Logical_Name,

Physical_Name, (size*8)/1024 SizeMB

FROM sys.master_files

order by SizeMB desc

and

exec sp_MSforeachdb @command1='use [?] exec sp_spaceused'

go

Actually this looks like what you need:

I just created the usp_Sizing sproc and it indeed returns a Free Space % column, along with lots of other statistics.

You can add FileProperty(Name, 'spaceused') to the first script above to get the space used in each file. YOu still need the calculation because this function returns pages not KB.

Thank you Jack and Seth, while not as pretty, I can make these work for what I need to do.

Microsoft: This isn't a unique thing to do, why don't you make it easy?

Thanks!
