How can I use tsql to find the physical location of a filegroup on SQL Server 2008?
Try this..
SELECT * FROM sys.database_files
OR
SELECT * FROM sys.sysaltfiles
Also
Use this script to see a more detailed picture of objects and their actual physical file names and locations.
SELECT OBJECT_NAME(i.id) AS Table_Name
, i.indid AS Index_ID
, i.name AS Index_Name
, i.groupid AS Group_ID
, f.name AS File_Group
, d.physical_name AS [File_Name]
, s.name AS Dataspace
FROM sys.sysindexes i
INNER JOIN sys.filegroups f ON f.data_space_id = i.groupid
INNER JOIN sys.database_files d ON f.data_space_id = d.data_space_id
INNER JOIN sys.data_spaces s ON f.data_space_id = s.data_space_id
WHERE OBJECTPROPERTY(i.id, 'IsUserTable') = 1
