Recovery from a KPF File Derived from a Reflowable ebook or Paperback Book Only

The simplest and quickest way to recover your master Word doc and master KCB project file from a KPF file is to do it in the following way:

Use a zip compression application like WinRAR or 7-Zip to open your KPF file as a zip archive.
Extract all files and folders in the archive to a new folder.
In the new folder, save and rename the "book.docx" file to another safe file location on your computer. The "book.docx" file is your master Word doc that you originally created and loaded into Kindle Create.
In the new folder you should also see another file called "book.kcb". That's the master KCB project file that you originally used in Kindle Create to create your uploaded ebook or paperback book.
Double-click on the "book.kcb" file and it should open in Kindle Create. This is the final version of your master file that you originally used to create your final KPF file for upload to KDP.
After making any changes required in Kindle Create, you can save the KC doc as a KPF file for upload if you wish. As well, you should also ensure that you rename and save your new master KCB project folder to a safe and unforgettable location together with the original master Word doc.

Just to also explain and emphasize that the master KCB file is the most important file to save because it contains both the Word formatting as well as the finishing touches that you added in Kindle Create. But the master Word doc only holds the Word formatting and none of the KC formatting. So the KCB file is the essential master file if you want to fix a problem or update your currently published ebook or book because it should contain ALL the current text, layout and formatting of your published book/ebook. In other words, the Word doc isn't really the file you want to recover -- the key file that you really need, for complete recovery, is the KCB project file.

Please also have a look look at the link below. It will help you to understand what I've just described above. The image is just a jpeg showing the innards of a KPF as a zip file.
