Hi - there is no direct relationship between the logical storage (tables) and the physical storage (datfiles). You can relate them by querying dba_extents. This will show the files containing extents of the table hr.regions:
select file_id,extent_id from dba_extents where
owner='HR' and segment_name='REGIONS';
You can take it from here! There are many other views you'll need to join in order to get a full, well documented, description of your storage.
