Why does Calibre Library take up so much space?

7000 books equals 50GB when exported. Most books in my library are epubs, and most of these epubs are 2MB on average I'm guessing. Yes, I do have some epubs that have many high-res images. Yes, I do have about 200 PDFs, some of which are image-based PDFs.

But I wouldn't think it would take 50 gigabytes? Are these one-gigabyte library000X.data slivers not compressed?

And what about the calibre-library itself (I mean, not just the "exported data" form)?
