Recently I noticed that book files that used to be azw or azw3 files on my Kindle have turned into kfx files (I guess amazon replaced azw3 files with kfx files), which are utterly incompatible with Calibre.
I am not even sure if the kfx files are actually the books themselves, or merely links?
Reasearch showed that downloading book flles with Kindle Application 1.17.1 (not newer than that!) allows me to doenload all books as azw files. I can find these azw files in my Mac in the user/library/application support/kindle/my kindle content.
The problem is that these azw files have file names that don't show the book title as part of the file name, as azw files used to show. Howver, if I open such a weirdly named azw file in Calibre, Calibre does display the book title anyway.
But I want to make backups for my azw files, and if I don't see the book tiitle as part of the file name, it becomes a messy process. Can I edit the azw file name to include the book title in the file name, or will this cause problems?

My workflow is to have my default device as "Kindle for PC", so that's where books get sent automatically when I buy them. Once a week or so I run K4PC, so all the queued books get downloaded. I then open the "My Documents\My Kindle Content" folder, sort it by date, and drag and drop all the books that have just downloaded (ie the ones at the top of the list) into Calibre. The filename is therefore entirely irrelevant, because the books appear with the correct title and author in Calibre.
