I cannot explain how you are seeing a description on import of books from your PW2. Perhaps you already had an entry in your calibre library for that book with the description before importing from your Kindle or something else in your calibre setup is providing it.

I've not gotten any descriptions from Kindle eBooks be it Mobi, KF8, or KFX.

Should I be using Calibre's Add Books instead? Or can the plugin be modified to also import the description on click and drag?

Despite what I posted earlier, books in KFX format can have a description field but it is not always present. If the book being imported has a description this plugin will pass it along as part of the metadata when adding a new book to calibre. As far as I know metadata is not updated if you are adding a format to an existing book entry in calibre.

I am not sure why it is working in one case but not another. I will look into it further. If you can provide the ASIN of a book that provides a description when imported from a PW2 but not K4PC that would be helpful.

Unfortunately, I can't. I've finished processing all my books. I did try again (3 ways) by buying a free book (link if anyone is interested https://www.amazon.com/gp/bestseller...0da8981a3b15#1), but I guess no description was included since all 3 ways failed to import one.

The freebie I bought was B0BZZHKKQG (Girl Who Lied). It seemed one of the least...romantic. Published 2023.

The 3 ways I imported the book:

Send to K4PC
My Kindle Content
search ebok.azw
click and drag to Calibre
No description, ever.

Add Books from Folders & Subfolders
My Kindle Content
No description this time. Rarely use this method. Will start using to see how often description imports.

Plug in PW2
Go to Device
Right click new book
Add to Library
No description this time. Method is rarely used.

Thanks for trying.

Howdy, and thank you for the work you put into the KFX plugins! I am running into an error with the exception "Book appears to have KFX containers from multiple books. (duplicate fragments)" I've tried the conversion with "Ignore errors" selected, and it still fails. Any help will be appreciated!

Here's the log:

Potential roadblock ahead! Amazon is trying to force K4PC users to update; this evening, I tried to sync a library book — a 25-year-old novel that has been out of print for a number of years — and K4PC showed the name of the book in the download area, but gave a message indicating that "features" in the book require an upgrade to K4PC. Digging into the K4PC folder, it downloaded only the title, the cover thumbnail, and a short hash string; it didn't even create a folder with the ASIN as its name.

That it is the first of May is probably not at all a coincidence. I will not install a new version of software due to undisclosed "features" of a 25-year-old novel... especially as buggy as every other K4PC release to enable undisclosed "features" has been.

I read library e-books on my laptop because I can get around some of the shiny marketing nonsense (and resize things) much more easily. I will be entirely unsurprised if even older library books have the same problem with new downloads. This, of course, is just foreshadowing for what Amazon will do shortly (if it hasn't already!) with newly-purchased items, or even for new downloads of previously purchased items.

It appears that the book you imported contains extra files that are interfering with conversion. I suggest removing the book from your device, downloading it again, and then importing it into calibre.

That happens for some books. Amazon has added features to KFX format over time and checks the features present in each book against those supported by the reading software before actually downloading it.

Would you mind sharing the ASIN of the book? It may be possible to determine exactly what "feature" is causing the problem.

That is to be expected since the book did not actually download.

It may just be a coincidence. This has been going on for a long time with various books based on their internal formatting.

Amazon is again in the process of tightening the security of Kindle ebooks and I fear things are going to become worse. I am just unsure that this particular case is an example of that.

That did it. Thank you!

Version 2.24.0 - 04 May 2025

Add the ability to cancel a conversion being performed using "From KFX".

Ma'am-I-Am · 05-07-2025, 08:00 PM

I just had something interesting happen. I imported a book which showed up as KFX-ZIP - and it opened! The MD file also imported, but the book is viewable even without it.
I'm just posting this because I've never heard of this happening before. Has it?
Still not getting descriptions imported, though.

I see that regularly. I have been assuming that it happens for books without DRM.

A failure to remove DRM is the most common reason to end up with KFX-ZIP format, but it is not the only reason that can happen.

A calibre debug log would be helpful in discovering the cause of the problem. Here are instructions copied from the DeDRM FAQ: Remove the DRMed book from calibre. Click the Preferences drop-down menu and choose 'Restart in debug mode'. Once calibre has re-started, import the problem ebook. Now close calibre. A log will appear that you can copy and paste.

You will see a MD file if you ask calibre to import everything in a Kindle for PC book folder. In this case K4PC uses the .md file extension for a metadata file but calibre see that extension as being Markdown format. If you do not have a need for Markdown you can prevent this by going to Preferences, Adding books, Adding actions, Rules to filter added files, Add rule, Ignore if the filename ends with .md, Ok, Apply.

It does happen occasionally but not to me. It would be good to have a log in order to diagnose it.

Again, I would need to see a case where a book that actually contains a description in KFX format fails to import with it. Most books do not contain that metadata.

Again, a log would be helpful, but only if the book converts successfully without a DRM error. Problems with DRM removal should be reported instead to NoDRM's GitHub.

Connect your Kindle to your calibre library via USB. Then drag/drop the .kfx files from the Kindle to calibre. The KFX Input plugin will handle getting the other files needed off of the Kindle and adding them to the .kfx so the DRM can be removed.

Amazon is trying to force K4PC users to update; this evening, I tried to sync a library book — a 25-year-old novel that has been out of print for a number of years — and K4PC showed the name of the book in the download area, but gave a message indicating that "features" in the book require an upgrade to K4PC. Digging into the K4PC folder, it downloaded only the title, the cover thumbnail, and a short hash string; it didn't even create a folder with the ASIN as its name. That it is the first of May is probably not at all a coincidence. I will not install a new version of software due to undisclosed "features" of a 25-year-old novel... especially as buggy as every other K4PC release to enable undisclosed "features" has been. I read library e-books on my laptop because I can get around some of the shiny marketing nonsense (and resize things) much more easily. I will be entirely unsurprised if even older library books have the same problem with new downloads. This, of course, is just foreshadowing for what Amazon will do shortly (if it hasn't already!) with newly-purchased items, or even for new downloads of previously purchased items.

I did try again (3 ways) by buying a free book (link if anyone is interested https://www.amazon.com/gp/bestseller...0da8981a3b15#1), but I guess no description was included since all 3 ways failed to import one. The freebie I bought was B0BZZHKKQG (Girl Who Lied). It seemed one of the least...romantic. Published 2023. The 3 ways I imported the book: Send to K4PC My Kindle Content search ebok.azw click and drag to Calibre No description, ever. Add Books from Folders & Subfolders My Kindle Content No description this time. Rarely use this method. Will start using to see how often description imports. Plug in PW2 Go to Device Right click new book Add to Library No description this time. Method is rarely used.

I imported a book which showed up as KFX-ZIP - and it opened! The MD file also imported, but the book is viewable even without it. I'm just posting this because I've never heard of this happening before. Has it? Still not getting descriptions imported, though.
