Couple of days ago, Calibre shut down without warning and when I re-opened it, I got a corrupted database message. I was able to successfully restore the database but I have noticed something weird.

When I click on a specific title within Calibre, the are no formats showing. I typically keep both mobi and epub for all of my books. When I click on the path and it opens the Calibre folder for that specific book, I see both formats along with a cover.jpg and metadata.opf file which is what I would expect.

Why if the files exist in the folder are they not showing in Calibre? I hope this question makes sense and more importantly, how do I get the formats to show back up in the database? I hope someone tells me that I don't have do each and every file individually because if I do - well that is definitely going to take some time.

One final question: is there a limit to the number of books one can have in Calibre? Is there some threshold or ceiling at which this database starts to go crazy? Just wanted to check.
