Hi,
In addition to Prashanth’s suggestion, you can also use the following Transact-SQL statements to get more detailed information including  all objects and indexes per Filegroup / Partition and allocated data size of databases.
The script can work with Microsoft SQL Server 2005 and higher version in all Editions. For more details, please review this article:
List all Objects and Indexes per Filegroup / Partition.
-- List all Objects and Indexes
-- per Filegroup / Partition and Allocation Type
-- including the allocated data size
SELECT DS.name AS DataSpaceName
,AU.type_desc AS AllocationDesc
,AU.total_pages / 128 AS TotalSizeMB
,AU.used_pages / 128 AS UsedSizeMB
,AU.data_pages / 128 AS DataSizeMB
,SCH.name AS SchemaName
,OBJ.type_desc AS ObjectType
,OBJ.name AS ObjectName
,IDX.type_desc AS IndexType
,IDX.name AS IndexName
FROM sys.data_spaces AS DS
INNER JOIN sys.allocation_units AS AU
ON DS.data_space_id = AU.data_space_id
INNER JOIN sys.partitions AS PA
ON (AU.type IN (1, 3)
AND AU.container_id = PA.hobt_id)
OR
(AU.type = 2
AND AU.container_id = PA.partition_id)
INNER JOIN sys.objects AS OBJ
ON PA.object_id = OBJ.object_id
INNER JOIN sys.schemas AS SCH
ON OBJ.schema_id = SCH.schema_id
LEFT JOIN sys.indexes AS IDX
ON PA.object_id = IDX.object_id
AND PA.index_id = IDX.index_id
WHERE OBJ.type_desc='USER_TABLE'-- add this WHERE clause to display the information of user tables
ORDER BY DS.name
,SCH.name
,OBJ.name
,IDX.name
