Here is a trivial script to show where a particular index resides. It saves clicking around the SSMS GUI.
1 2 3 4 5 6 7 | SELECT i.name, i.type_desc, i. is_primary_key, i.is_unique, s.name AS [Filegroup] FROM sys.indexes i INNER JOIN sys.data_spaces s ON i.data_space_id = s.data_space_id WHERE i.name IS NOT NULL AND i.name NOT IN ('clust', 'clst', 'nc1', 'nc2', 'nc3', 'nc', 'cl') ORDER BY s.data_space_id, i.name |
