I have a large folder of a number of books. Instead of looking for an indexing solution to keep track of what's in there, I thought I'd give Calibre a try. My only issue is that I am not keen on 'duplicating' my large folder of books to another folder (Calibre Library).
Is it necessary to copy all of the books? Or is there a way of having my existing folder of books become the Calibre Library itself?
