How can you completely remove a package?

I have learnt that using purge command rather than remove is considered better because purge removes all files related to an app including the config files etc.

Now this has happened before too but as now I dont remember those examples I state my latest encounter-

The Problem-

even after purging,some files remain!

Latest encounter-

cuttlefish( the app from the showdown)

I purged cuttlefish as it was nor working properly whatsoever and then restarted Ubuntu(although that is not necessary) and then re installed it to already find some trigers I had made in the app before deleting it already present! which meant some file(config or something) was not cleared out !

Now i tracked down 2 files in a folder(.cuttlefish) under home and found some files related to plugins and a reflexes.db file(which seems to be the one responsible to contain the triggers i got back on re instal)

I deleted them mannually and did the re install.Though m still facing other problems with the app,Why dint the purge command remove these files?

Thankyou!
