I see one other question here regarding this topic, but no answer is accepted, and nor do any of the files/file formats mentioned in those answers match the filetypes I see.
I work on two monitors and when using docs, like to have the doc open in a decent PDF reader - much better UX than the simple Windows 10 Kindle App, which I don't like very much.
When I connect my Kindle to the PC, and open its
documents folder, I find my book in a folder with its title as name and
.sdr as its extension. This folder contains 3
.asc files, and one
.azw3f and one
None of these files are large enough for a book, but it does show under "Downloaded" when I check it on my kindle.
Is there any way I can go about using these files to covert the book to PDF, or is there a special converter I can just pass the whole
.sdr folder to and have it do all the conversion "paperword"?
