Can't Import Calibre Library Files

[EarthlingSil]

So I'm getting this error every time I import my Calibre books I had backed up the previous night on an old computer.

I'm truly baffled and have no idea what to do. My old PC has already been wiped and taken apart and I'm on my new PC.

Here's what the files I'm trying to import look like.

Did something go wrong? Those are the files Calibre gave me when I exported my library. I have over 1k books and I'll be devastated if I can't get them back.

Just wondering why part 3 and part 5 have a jpg extension?

I'd love to know as well, but thats what Calibre kept giving me when I exported my entire library. I've exported multiple times the past couple of weeks and kept getting that.

I'm real worried something went wrong, I just don't know what.

Edit: I have some of my library backed-up as actual epub files, but a good chunk of it isn't because I thought that's what choosing the Export was supposed to do.

calibre will never give you files with a jpeg extension when exporting. If you still have the original library folder you can simply zip it up and restore it, as described here: https://manual.calibre-ebook.com/faq...ter-to-another

Alas, I do not, as it's on my old PC that has already been wiped and taken apart.

I was afraid something that can't be fixed went wrong. I'll just have to slowly rebuild my library I guess.
