Kindle KFX/DRM Dateien konvertieren

[NaSowas]

Für Leute, die ihre Kindle KFX-Dateien bequem vom DRM befreien bzw. in das gängige Format epub konvertieren möchten, gibt es seit einiger Zeit das Programm Epubor, das allerdings in Deutschland aufgrund des UrhG nicht zulässig sein dürfte.

Hallo Otti,
zu beachten ist, daß sich die aktuelle Version Epubor Ultimate Converter 3.0.10.213 nennt. Bei P2P wird ihnen geholfen.

Gruß nach Austria!

Danke, aber ich habe bewusst die freie Version bereitgestellt

Bei P2P wird ihnen geholfen.

Ich lade die AZW3 nach wie vor von Amazon direkt nach dem Kauf runter. Das ist bequem genug für mich.
Ich denke auch nicht, dass Amazon diesen Download so schnell abschalten wird.

Ich habe einen Paperwhite 2 mit originaler Firmware und sende an: Übertragung per Computer

@Ottischwenk: Genau so. Oder aus dem Bereich "Meine Inhalte" runterladen, geht auch.

Ich glaube nicht, dass Amazon hier jemals KFX zum Download anbieten wird, denn KFX besteht aus mehreren Dateien und einer definierten Ordnerstruktur. Das ist auf diese Art nur schwer endnutzertauglich abbildbar.

Natürlich ist nicht auszuschließen, dass ein KFX-Nachfolger wieder als Container-Format herkommt.

Mit Hilfe des aktuellen DeDRM Tools 6.6.0 von Apprentice Alf (PlugIn für Calibre) schafft es mittlerweile auch Calibre, von Kindle KFX-Dateien das DRM zu entfernen.

Erläuterung aus Mobileread:

Importing KFX books into calibre for conversion:
Users of this plugin must manually import KFX books into calibre. They cannot be transferred using the "Device" view.

First, the main KFX file for the book to be imported must be located:

For Kindle for PC/Mac version 1.19 or greater the "My Kindle Content" folder will contain a sub-folder for each book, named with the ten character ASIN of the book followed by "_EBOK". The ASIN for each book is shown in the "Product details" of the book's Amazon web page. The main file for the book will have an ".azw" extension, regardless of whether or not it is in KFX format. When locating books it may be helpful to sort "My Kindle Content" by date so that the newest book sub-folders appear first.
On e-ink Kindle devices connected via USB, the main file for each book is contained in the "documents" folder. These contain both the title of the book and the ASIN. Books in KFX format will have a ".kfx" extension.
No workable import method currently exists for Fire tablets or the Kindle for iOS/Android apps.


Once located, the main file can be imported to calibre using "Add Books" function ("Add books from a single directory") or using drag-and-drop.

Be patient. The import process is complex and may take a minute or more to complete for a large book.

If successful the result will will appear as KFX format in the calibre library. This can be sideloaded to Kindle apps & devices, viewed using Kindle Previewer 3, or converted to other e-book formats using this plugin.

If the resulting format in calibre is KFX-ZIP instead of KFX then the import was unsuccessful. Information on the reason for import failure can be obtained from a log file. Click the calibre Preferences drop-down menu and choose "Restart in debug mode". Re-import the book and then close calibre. A log file will appear.

Import - Behind the scenes:

Calibre handles all e-book formats as a single file, however books in KFX format are usually composed of multiple KFX container files. When the main file of a book in KFX format is imported in calibre a File Type Plugin contained within the KFX Input plugin will automatically locate the rest of the files that make up that book and gather them into a KFX-ZIP archive (a ZIP file with the extension ".kfx-zip".)

If the DRM removal plugin with KFX support is properly installed and configured it will process the KFX-ZIP and remove its DRM.

The KFX-ZIP archive will then be processed again by the KFX Input plugin to package the content into a single monolithic KFX file.

Converting from KFX to other formats:
The KFX Input plugin is activated by selecting either (Monolithic) KFX, KFX-ZIP, or KPF as the input format when converting books in calibre. A command line interface is also available. (See below.)

Monolithic KFX format will be produced when a KFX book is successfully imported into calibre. See "Importing KFX books into calibre" above for instructions. Monolithic KFX can also be produced using the KFX Output plugin.

Note: Monolithic KFX is different from the files delivered by Amazon with a ".kfx" extension. Those contain only part of the book's content and cannot be converted individually.

Amazon's Kindle Textbook Creator and Kindle Create software export books in KPF (Kindle Package Format), a KFX variant proprietary to Amazon. This plugin allows conversion of KPF, so that the author has greater control over the finished book.

This plugin will fail to convert files that contain unexpected data, such as new or uncommon KFX features. You can force conversion to proceed despite these errors by selecting the option "Allow conversion to complete even if errors are detected" in the KFX Input tab of the conversion dialog. However, in that case the results of conversion may be incomplete or incorrect.

If the option to ignore errors is selected or if the results of a conversion appear to be incorrect, it is recommended that the conversion job log be checked for errors and warnings. Please report problems in this MobileRead thread.

You can view the conversion job log after an error occurs to see additional information on why the conversion failed. To access the log, either click on the "Jobs: 0" label in the lower right corner of the calibre window or use the Alt-Shift-J keyboard shortcut to activate the Jobs dialog. Select the failed conversion job from the list (the most recent will be first) and click the "Show job details" button. To copy the log to the clipboard under Windows, click within the log text then press Ctrl-A (select all) and Ctrl-C (copy). You can then paste it wherever you like.
