How to prevent Delphi from generating bpl, identcache and local files

Delphi generates a series of annoying and useless files such as *.bpl, *.identcache and *.local. They are totally useless and safe to delete.

Few people know that Delphi Distiller is capable to disable the generation of these files. This is because the panel from where you do this is hidden under an obscure menu called 'Extras'. Just download Delphi Distiller and see for yourself. 

Piece of cake. Right?
