i have a related problem - I want to make a duplicate of my existing library and use it to test some batch processes, but I can't get it to work.
i tried the obvious - make a calibre library 2 folder & copy everything into it, then point calibre at that new folder - but it says no books!. so then I tried "save to disc" to save all books from original library into new folder - still get no books when I tell calibre to use that new folder as a library.
so what the proper way to do this - I assume there is one ?
as for why - well I set up the original library to store separate covers. when I send books to kindle 3 the covers don't show up, so I figure I have to re-convert every book from mobi to mobi but with save separate covers turned off in preferences. I wanted to run this on a duplicate library in case anything went horribly wrong. so now I'm having to run it on original library & hope for the best. did I miss a better solution ?
