Transferring my Nook SD ebooks to Calibre
 

My computer's hard drive died so I've now got a new computer and I've re-downloaded Calibre. I've got all my ebooks in my Nook's SD card, how do I move all my ebooks from my Nook to my new Calibre?

I know that I can do it one at a time but is there a way to bulk move the ebooks?

Thanks!

Yes, see the dropdown on the Add books toolbar button.

"Add books from directories, including subdirectories (multiple books per directory, assumes every ebook file is a different book)"

You can also go to the device listing and select a batch of ebooks, then right-click and select "Add books to library".
