f.name as filename
FROM (((sys.tables AS t
INNER JOIN sys.indexes AS i
ON (t.object_id = i.object_id))
INNER JOIN sys.partition_schemes AS ps
ON (i.data_space_id = ps.data_space_id))
INNER JOIN sys.destination_data_spacesAS dds
ON (ps.data_space_id = dds.partition_scheme_id))
INNER JOIN sys.filegroups AS fg
ONdds.data_space_id =fg.data_space_id
innerjoin sys.database_files f on f.data_space_id = fg.data_space_id
where t.name='salesOrder'
