It’s unclear how long Amazon will support these older versions, or that they’ll be available for download. Once you have, go to the Tools menu, then Options, then General and uncheck the box to install updates automatically-and then just don’t update. The only way to resume being able to convert downloaded Kindle content is to uninstall Kindle for PC, then reinstall Kindle for PC version 1.17, currently accessible via this link (or this one for the OS X version). Instead, it uses the new KFX ebook format-which nothing else can read or convert right now. It turns out that the new version of Kindle for PC, 1.19, no longer uses the AZW ebook format that Calibre knows how to read. Even though it’s DRM-free, when I dragged and dropped the file from my “My Kindle Content” directory across to Calibre, it couldn’t figure out what to do with the file.Ī little detective work turned up this Mobileread forum thread. I noticed it myself when I was trying to add a DRM-free title I just bought, Bone Dance by Emma Bull, to my Calibre library. Things just got a little harder for folks who like to store their Amazon purchases in Calibre. So, there may no longer be any need to use these workarounds. Update, 4/5/18: I just noticed a post in a MobileRead thread indicating that there are now Calibre plug-ins available for handling KFX.
