Open KFX with Kindle Previewer 3

KFX files produced by the KFX Conversion Output plugin or imported using the KFX Input plugin can be viewed using Kindle Previewer 3. However, the Previewer supports the file extension .azw8 for opening KFX files instead of .kfx. In order to open a KFX file with the Previewer it must first be copied or renamed so that it has a .azw8 extension.

The "Open KFX with Kindle Previewer 3.bat" script can be installed in Windows to allow files with a .kfx extension to be viewed more easily.

Installation:
  • Kindle Previewer 3 must already be installed for the current user.
  • Download the .zip file attached to this post.
  • Extract the enclosed "Open KFX with Kindle Previewer 3.bat" file.
  • Place this .bat file in a permanent location of your choice on the PC.
  • Right-click the .bat file and select "Run as administrator". The script will report success or failure. Press enter to close it. (This will associate the script with .kfx files. Repeating this step will remove the association.)

Once associated the script file will execute whenever .kfx files are to be opened.


Usage:

Once installed you can then select a converted book in calibre and in the "Formats" section of the book details panel and simply click on "KFX" to open it with the Previewer. The .kfx file will be copied to a temporary .azw8 file and opened with Kindle Preview 3.


Limitations:

This script uses a simple method to create the file type association, not the best possible method.

A Command window will briefly pop up whenever the script is activated.

It has only been tested under Windows 10.

It is not available for MacOS or Linux.

Version History:
Spoiler:


Version 1.0.0 - 24 Oct 2016
