Hmmm, After reading this topic with interest (thanks for the laugh Manichean by the way
) I learnt something about calibre that I didn't already know. I'm a shift del kind of person and kind of ignore the recycle bin. I always thought that when I deleted or merged titles in calibre that they were just deleted. I've just now checked my recycle bin and after a year of playing around with calibre, deleting, starting new libraries, changing my mind, starting again, tidying etc (can you see the ocd in me?) my recycle bin has 60GB to be deleted! It seems there are always more things to learn about calibre, and that's just a simple example.
