Hello again, as the title says, I have a lot of info I add to calibre while simply dragging into the monitored input folder. While I am really happy that it is all converted to epub as is, I was wondering if there is a way to have PDF files exempted from this conversion process and be added in their original format and left alone as most of these are instruction guides and plans that have large hi-def images that are best left as pdf and viewed as such since they can be edited from time to time.
