Some Kindle books can't be read (no AZW3 file)

MarkMobileR · 07-04-2019, 12:31 PM

I am using Calibre to try to convert my Kindle books. I am on a Mac, I've installed the DeDRM plugin, and I did the chmod on the renderer-test file. My kindle version is 1.26.1 (55096).

I have 99 books in my Kindle App. But Calibre only reads in 88. To try to troubleshoot... I deleted all the Calibre books, and began to drag in each azw file from each cryptic kindle directory manually.

Finally, I came across a kindle directory that only has the following files (extensions):
.apnx
.kcr
.mbpV2
.phi
AND a "resources" subdirectory with tons of files with filenames with numbers.

Calibre can't seem to deal with this file structure. Can anything be done? What am I looking at here?

Thanks! Mark

you are looking at .KFX format.
best avoided

for simplicity, roll back to K for PC 1.17 and re-acquire the books, but see a recent thread with AZW in the title , on how to overcome problems when going that route

The .kcr file indicates that this book is in Kindle Cloud Reader format. This is the same format as is used in the Kindle for iOS app. Kindle for Mac uses this format in place of KF8 (azw3) starting with version 1.25.

More information on how to handle that in this post.
