They are seldom used (I have only seen them with a p2p utility), and right now, I do not remember how to find out if they exist on a partition.
Neither do I, right now, but IIR it's pretty normal for database files to have such for a number or reasons, ranging from unused field pace, blanks in the record or gaps due to the indexing.
Maybe because records are deleted in the middle of the file. They are emptied, the sectors given back to the filesystem, which can reuse then on another place even for the same database file, now at the end :-) -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
