It's all very weird. Now the app won't tolerate more than 4900 files in the My Kindle Content folder (at least "old style" files -- pre-kcr), where it used to handle 25,000.

Along with the Firefox problems I've been having, I wonder if this is a memory issue with Catalina. I have seen various grumblings about memory leaks and other memory issues, so I have my suspicions. But I am not nearly savvy enough to know anything useful in that area!

I can't find a repo or any way to make a pull request, so I'll just post here. This is a small fix for when Kindle Previewer is installed in a different folder.

I'm not a developer, so I can't tell what the pull request is for, but if it's for Alf's plugin, you can make a pull request on GitHub here: https://github.com/apprenticeharper/DeDRM_tools/pulls

If it's for Calibre's overall program, kovidgoyal's GitHub is here: https://github.com/kovidgoyal/calibre/pulls

If it's for a Calibre plugin, find the plugin page from this index then post there: https://www.mobileread.com/forums/sh...d.php?t=118764

Does that help?

Specifically for jhowell's KFX Output plugin that this thread deals with.

[nevermind, this answer is moot] - I see a moderator already moved this issue to the KFX Output plugin thread

Hi guys,

I am trying to remove the DRM for a Kindle book using the information in this thread.

Below are the software that I installed:

KindleForPC-installer-1.24.51068.exe
calibre-64bit-4.7.0.msi
DeDRM_tools_6.6.3.zip
KFX Input.zip (latest version 1.26.0 dated December 23, 2019)

The following are the steps I take to remove the DRM:

1. After synchronizing the Kindle For PC software with Amazon's servers, the ebook in question is downloaded to the custom directory.

2. Minimise the Kindle For PC software. Do not shut it down.

3. Launch Calibre software.

4. Install third party plugins such as DeDRM_tools_6.6.3.zip and KFX Input.zip (1.26.0 dated 12-23-2019).

5. Restart Calibre after successful installation of the plugins in (4).

6. Click the button "Add books" --> "Add books from a single directory".

7. Navigate to the custom directory where the Kindle book has been downloaded.

8. The said Kindle book shows up in the list of titles in Calibre.

9. When I double-click on the title, an error message says "This book is locked by DRM. To learn more about DRM and why....."

Your help is much appreciated.

+neyet,
You need to downgrade to Calibre to 4.5. In 4.6, Calibre changed the name of a library used by the DeDRM tools for KFX.

The procedures in the first post are applicable to books without DRM. The additional procedures needed for handling books with DRM are intentionally not discussed here as per the rules of MobileRead.

Please ask for help at Apprentice Alf's Blog or Apprentice Harper's GitHub for help with DRM removal.

Thanks - was wondering why my conversion attempt failed over the weekend.

Hi,

The below worked for me and was able to convert to epub & pdf

KindleForPC-installer-1.24.51068.exe
calibre-64bit-4.5.0.msi
DeDRM_tools_6.6.3.zip
KFX Input.zip 1.26.0

great tons of thanks for information and help rendered

I appreciate all your posts so much. I am trying to set my PC back to where I can convert books again. I deregistered my Kindle for PC, removed the My Kindle Content folder from my PC, downloaded Kindle 1.24 and the Kindle shortcut showed up on my desktop. But....I went to the Amazon website to register my PC as the default and my PC doesn't show up at all. Can anyone please help me? Thanks so much.

Did you try launching Kindle for PC? Not sure if PC and Mac are the same, but on Mac if you launch a totally new installation, it will prompt you to register. Likewise, if you've already registered, you can go to Preferences to deregister then re-register. All this registration stuff happens within the app, not on Amazon's website.

Once Kindle for PC is registered, then you can go to Amazon's website to set it as your default device.

Just confirming that Kindle for PC works the same. Sign into the app, and it will be on your list of devices on the website.

@odamizu, thank you so much for this -- it was just what I needed. I appreciate being able to ask a question and having it answered. :-)
