#   Check that a drop table removes all files belonging to this table.         #
#   Remaining unused files can be caused by imperfect DROP TABLE or            #
#   ALTER TABLE <alter partitioning>.                                          #

#   This routine is only useful for the partition_<feature>_<engine> tests.    #
#                                                                              #
