Where does Chrome stores offline books downloaded using Amazon-Cloud Extension on Windows 7?

Question

I've downloaded from Amazon a few books using the Chrome Cloud Reader extension.

The only possible way to view those books is from inside the Chrome Reader extension , and let's be frank , it's pretty much a very annoying extension .

I want to view those books (I guess .mobi files) in my own viewer (Calibre) , but I can't find the books that chrome downloaded (I'm working offline so I downloaded the books , but they're invisible) .

Where is Chrome storing those offline books?

Answer 1

So this doesn't directly answer your question, but if you're trying to find the .mobi files for use with Calibre, I would just download the Kindle for PC application and find the downloaded files for importing into Calibre.

They're stored in...

• Windows: Libraries/Documents/My Kindle Content
• macOS: ~/Library/Containers/com.amazon.Kindle/Data/Library/Application Support/Kindle/My Kindle Content

Answer 2

I think I've found where it stores them, but you won't like it.

C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default\databases\https_read.amazon.com_0

Contains a couple of files that don't have file extensions. They are SQLite 3 files. If you keep track of the file size and last edited time when you download a book, it gets bigger and is modified at the same time. Having potentially found the book, I still didn't get anywhere. Looking at the database in Sqlite Browser, it seems that the books are broken apart into thousands of fragments.
