Dealing with Kindle ebooks in calibre

Then it must be two plugins, a File Type plugin that runs when when a book is added, and a Conversion Input plugin that runs when a format file is Converted - afaik, a single plugin cannot do both.

Someone who has the plugin installed (not me) needs to look in their list of installed plugins and provide a definitive answer.

Nope, it's only listed under File Type plugins.

And it's 7.2.1.

10.0.9 in my case.

I wonder why it's showing as kfx-zip. What am I not understanding here?

I have that same thing happen. I have had DeDRM for about 12 years and every instance of a Kindle key update, it's in my list. Turns out that having all those keys when it updated to the newest verson caused my Kindle files imported directly from the Kindle or the Kindle for PC app to be kfx-zip. They are unlocked, but still kfx-zip.

It wasn't until I deleted all my old kindle for pc/mac keys and just had the one that's current running that I was getting .kfx only!

File Type plugins can choose do their thing at several different places within calibre. The initialization function in DeDRM has:

    on_import               = True
    on_preprocess           = True

Where "preprocess" is the first step in conversion before the input plugin is invoked.

Oh! Now that you mention it, I have fuzzy memory of DeDRM now running on import, conversion and viewing. I will update the first post. Thx!

Amazon is tightening the noose even further: my K4PC 2.4.0 just updated itself overnight (to 2.6.something). This is with automatic updates disabled in the app and, more important, with the update block (the %LocalAppData%\Amazon\Kindle\updates file) in place. Reinstalling 2.4.0 over it worked for now, but I fear this hole is going to be plugged soon.

OK, so I have upgraded Calibre to 7.26 and DeDRM 10.0.9. When I plug in the device, I see lots of files, some of which are not marked as being in the library. I have been having to do the match book to library thing to get them connected* and I guess i forgot in the last batch of updates. If I do the Customize Plugin thing for eInk, I see two serial numbers, neither of which is my Paperwhite. Since for ages I have been doing the updates with the soon to be missing USB transfer, I guess it didn't need the serial number of the Paperwhite, but now it will, so I should add it. As for the warning about the cover, if the books are going from Kindle to Calibre, I guess this is not an issue.

* I suppose this is a difference in format issue and should go away with files now originating on the Kindle.

Download & Transfer definitely required the serial number to remove the DRM (if the book had it - not all books have DRM). But you may have used another device as the target.
