Hi David,

Thank you very much for your reply. I really appreciate, and your message "turned on some lights".

Guess what... I was not aware of, it's why I didn't mention...
Basically, I made some tests, I think one year ago, about the difference epub, Kepub, and the added-value a kepub may provide. Finally, I decided that's not really worth... At that time, I activated the extension and... I forgot to deactivate it. So... first action when I read your message: I deactivated the extension and checked all the other ones Maybe this was also the issue I faced when I tried to upgrade 3.18 to a newer version... Let's check.

Here, I have to say, I'm surprised. In fact, I read the code, but was not able to understand. In my library, I see one single format, which is epub. No Zip format at all... How can it be that Calibre tries to unpack a zip, which is not available in the format?

But, I have been discussing this elsewhere and that person is using an account with 60K purchased books in it. I could see issue during the import if you tried to do them all in one go.

For sideloading, if there is a problem with a book, then it can block the rest from being imported. If you are seeing the import screen after ejecting without adding a book, then this is probably what is happening. Unfortunately, there isn't any indication of which book causes this. You have to use trial and error to find it.
So, I know that the error is between 20999 and 22000. Not bad for a start

I'm curious about what is going on, so I'm doing some tests. Unfortunately, the biggest spare card I have is 16GB. I'll see how far I get with that, but I might get a bigger card on the weekend. I'm just adding the same 1145 books multiple times. I know they load OK, so they should work for this.
On my side, I'll start a new test with the Glo HD (same config), which is already ready to start... just to see if I face the same error... or a similar one... or no issue at all :-)

I'll need some time to get there, but anyhow, will keep you posted.

Thanks again for your support and I wish you a very nice day.
