Objects that goes to primary filegroup

Hello everybody, 

I have one database, that have around 2k tables and indexed views.  teorically data on most of them should go to separated filegroups we have on different hard disk, and none of them should be set to primary filegroup. 

I need to identify objects (tables, views, index) that goes to this primary filegroup, so I can change it and move it to their appropiate filegroup. 

Is there any query I can check to get the object list ?
