decide I'd have to get stuck in & re-test.
so I read lots of threads - got even more confused. #4 cybmole 10-18-2014, 09:39 AMupdate - I realised that I was hopelessly confused on this issue. mobi files, but also that the mobi format does not support all of the epub-like functionality that azw includes, so calibre: epub -> mobi -> kindle or calibre: azw3 -> mobi -> kindle could lose some formatting ? I read that is is relatively easy to sideload. general non-drm epub, withouth downgrading to mobi format de DRMd epub purchase, converted by calibre to AZW3 Or maybe I have to manually lose the "3" - a dummies guide for this would be good, covering how to sideload from PC / from cloud storage. its probably looking for some field or code that identifies is as a genuine book-from-amazon. The obvious route of epub -> azw3 in calibre then send to device, never worked when i tested it. Maybe it accepts some books, some of the time, but if so, I cannot figure out the criteria, Plain PDF files often lack such a security.#3 cybmole 10-18-2014, 06:44 AMthe same limitation is there when I move azw via usb, either manually or with calibre, or via dropbox my kindle fire does not accept them as books E-books may or may not contain encryption and security measures to allow only the authorized people to read them. This meta information is required to identify the book and to know about its various properties.Įncryption is yet another aspect that makes a proper e-book different from a plain PDF file. You can convert any file into a PDF file but to make it a proper e-book, this PDF file should contain all the required meta information. Whereas E-books contain hidden meta information about the book itself and about the author, publisher etc. That is one of the major difference between an E-book and a PDF file.Īnother big difference is that the original plain PDF format did not have the embedded meta information. Most of the PDFs are not designed to be reflowable. E-book will automatically adjust the content according to the screen size. Reflow means that the same e-book can be read on devices of different dimensions. E-book formats like EPUB, MOBI and AZW, support reflow of the book. But the modern and popular e-book formats have more features than the plain original PDF. Well, actually a PDF file is indeed an e-book.
But when they see so much talk about e-books they begin to feel that an e-book must be something more sophisticated than a simple PDF file! As we all have been seeing PDF files since we have learnt to use computers, a large number of people feel that a PDF file is an e-book.
