Download to Kindle has a problem

Agama · 12-04-2017, 04:13 PM

I've been using calibre to sideload my Kindle books to my Paperwhite for some years now and with no problem.

However, today I did this and the book did not show up on my Kindle's interface. Using Windows Explorer I could see that calibre had created a folder with extension .sdr and within this a file with an extension .apnx, but no sign of an .azw3 in this .sdr folder - presumably the reason why no book showed up - but there was an azw3 in the parent documents folder.

I noticed that whilst most books on my Kindle had an .sdr folder a few others did not so I deleted the .sdr folder for this failed book, ejected my Kindle and checked again. The book showed up immediately.

Is this a known issue? Perhpas if I just copy the .asw3 file directly to my Kindle's document folder then all will work? Do I even need the .sdr folder?

My Kindle never goes on WiFi as I don't appreciate Amazon messing with my collections and is at firmware 5.7.2

azw3 files dont belong in sdr folders. The sdr folder has to alongside the azw3 file.

Thanks. Looks like it should've worked then but it didn't until I deleted the sdr folder, so I guess something glitched on my Kindle. Can I get away without this folder, (the book seems to work properly), or should I resend from calibre to get it restored?

The folder will be created by the kindle when necessary, so there is no need to re-create it.
