Kindle PW can't open MOBI output, no prob with PC app
I've been using Calibre for a long time to convert EPUB files to MOBI for use with my Kindle PW (latest model). I'm currently using Calibre 3.2.1, and for some reason recently I can never open its MOBI output on the PW. If I try to email it (or Send to Kindle), it never appears, and if I sideload via USB, it says it can't open the file. But the same file works fine with the Kindle app on Windows 10.
The only way I can use it now is to convert to AZW3 and sideload it via USB, because for some reason AZW3 doesn't work with email or Send to Kindle. Any suggestions, please? |

Covert to KF8 and side load via USB. You really don't want Mobi. It's an obsolete format and you could lose some formatting. Forget Send to Kindle exists. Amazon sure does care about it or it would work with KF8.

Thanks, but why is MOBI an obsolete format? First I've heard ...

In case anyone else who's in my shoes reads this, I'll unpack JSWolf's response as best I can. Calibre doesn't output KF8 format per se, but there is a KFX-output plugin that seems equivalent. Here's the info: https://www.mobileread.com/forums/sh...d.php?t=272407
I converted to KFX and sideloaded no problem, but I wonder why I went to all that trouble (installing a plugin and a preview installer; whew!) when AZW3 seems perfectly compatible. I also tried Send to Kindle, and emailing to my @kindle.com address; the latter both with the original .KFX extension and renamed to .KF8. None of those worked. |

People have had success with using dual format MOBIs. In Calibre Conversion Dialogue: Output Format: MOBI MOBI output > MOBI file type: Both (old MOBI6 and KF8 formats together) Amazon usually accepts those and your device receives the KF8 format.

Thanks, JimmyR. I have to wonder how a malformed file on the PW would interfere with simply receiving and listing a book sent via Send to Kindle. Especially when it works fine with mobi files I didn't convert.
I tried your suggestion for File Type: Both and that worked. But that would mean double-size books filling up my PW. I guess I'll just stick with azw and sideloading. |

IF you haven't tried already, restart your PW. Also, try restoring the MOBI output settings to default. Could be a weird setting: Convert Book Dialogue Output Format: MOBI Restore defaults (bottom left) A similar problem: https://www.mobileread.com/forums/sh...53#post3052053 Quote:

All the books in my library are converted to EPUB and edited then converted to AZW3 if destined for a Kindle. |

PW4 unable to open sideloaded mobi
I know this is a four years old topic, still It had the solution for a problem of today.
I tried to sideload a set of books originally in epub format using the reliable method of silent converting by Calibre. The books however were unable to open on the device, even if the ebook reader in Calibre did handle it well. The resoulution of the problem was (as suggested in this old topic) to use KF8 (AZW3) instead of mobi. So thanks @JSWolf, this comment helped me after an hour long trying and confusion. (I still don't understand why but at least it works, however I will most probably never fill up the 32GB memory of my PW4 with text e-books even if I were to use double format files) Some answers of possible future questions: Yes, I had used mobi as default format for PW4. Yes, I have changed it now to azw3. |
