[Device Plugin] Kobo Touch Extended Driver

Not directly, no. The kobo driver (the main one in calibre, not this one) tells calibre how to read the library but that’s just a thing that can be done because that’s also how the driver knows what books are already in the device. Calibre can leverage that to know where the KePub files are in the device, which are able to be treated as ePub, and use its existing import functionality to copy the ePub over to the calibre library.

You left out the critical step, you renaming the file. That is what it takes to make it work, and what the driver would be required to do.

Also, importing might not even be necessary because the metadata is already in the device view. I just want to make an empty book from that metadata.

That would be a change to base calibre, possibly doable by a user interface plugin (not a device driver). You could make an enhancement request.

For this to work in your case the driver must make a copy of the book (how, if the book is virtual?), rename it, then give that path to calibre to import. DeDRM might get involved. You would still be required to delete the epub from the library. I don't know how fragile the process would be.

For copying books synced from Kobo into calibe, the OBOK plugin which comes as part the DeDRM package is the easiest route. It will import selected books from the ereader into calibre taking care of the renaming and/or DRM removal. It does require that the book has been downloaded to the Kobo so click on Download all from the Books view hamburger menu.

I'm having issues with sideloading certain epubs to the Kobo Libra Colour (books that otherwise work fine on my previous Kindle).

I'm trying to load "The Dark Forest" and if I use Calibre to sideload it on my Kindle Paperwhite it works just fine. However, using KoboTouchExtended (even tried just KoboTouch) I get a .epub.kepub file that behaves strangely.

By that I mean that it goes to a certain page of the book no matter what page I was in before exiting the book. It's something that happens every time I switch books. It only happens with one of my books so far. Although this is a new device so I have not read many of my books to confirm whether or not this is common.

Also, the UI menus to skip chapters and to seek a page are just very clunky and glitchy (just for this book).

Things I've tried:

1. I re-downloaded the book and I can confirm that thousands of other users have downloaded the same copy. So the file itself should be free of corruption I would imagine.

2. I used the "Quality Check" plugin and made some namespace, container, etc. checks but it found nothing wrong with it. However, I didn't make ALL checks since the plugin has like 50 options to choose from. I which there was a "check everything" option in the plugin. If anyone has any advice as to what to check let me know.

3. I loaded the .epub manually to my Kobo without using Calibre and it works just fine so the issue is either Calibre or the conversion to .kepub using KoboTouchExtended.

Problematic file in question:

If your original download from Amazon was azw3, you could use the KindleUnpack plugin to get the ePub rather than using a calibre conversion. I purchased this book from Kobo and it renders without noticeable issues on my Kobos.

You might also want to try kepubify to convert external to calibre and then sending that kepub.epub file to your Kobo. The KTE extended driver has had some issues reported.

You did read that he loaded it to his Paperwhite from calibre? This made me wonder if the original may have been an Amazon purchase. One that was downloaded from Amazon and then converted to ePub. If he purchased it from Kobo, it would have synced to his Kobo and would not have required him to use the KTE driver.

OTOH, he also stated that when he used the KoboTouch driver, it was sending a .kepub.epub file to his Kobo. This would only happen if he already had a .kepub.epub in his library.

Oddly on my Sage, I do not notice any issue with opening either Year 3, Crisis Era or Year 208, Crisis Era which are ~400K files.

If I am correct and this ebook was originally from Amazon and he used calibre to convert it to ePub, the default settings would be having those files split so that is unlikely to be the issue.

Thanks for mentioning the KindleUnpack plugin. It will help me solve a different issue I have with a book that is originally in AZW3 format. But in this case, the original file is an EPUB file (exact same file you can download in the link above, the link will expire after 10 downloads btw).

When I load it to my Kindle PW it gets converted to KFX and it works fine. So I'm not loading an AZW3, untouched, on my Kindle. That same source EPUB file gets converted to a file ending in `.kepub.epub` thanks to KoboTouchExtended (I assume) when loading it to my Kobo Libra Colour.

I tried kepubify and it looks like that did it! However, I loaded the `.kepub.epub` file by copying it to the Kobo Libra Colour manually using the file explorer. I didn't use Calibre since I think the KoboTouchExtended plugin will always convert EPUBs itself. Also, I can't add the file as a separate format to Calibre since it ends in `.epub` so Calibre will replace my original (existing) EPUB file which I want to keep too.

However, I'm confused about this part:

I don't have a .kepub.epub file in my library. Doesn't KTE auto convert EPUBs to .kepub.epub files itself? That's why I see a different file extension in my Kobo without having anything stored in my Calibre library right?

In my case, it goes to the same place in the book and stays there no matter where I finished reading. I also have other issues like the UI freezing for that ebook only depending on what I'm doing. If you use the KoboTouchExtended plugin to convert the epub file in the link above to a kepub you should see the same thing on a Kobo (hopefully).

If you use kepubify's for calibre option, it will generate a .kepub file and calibre will change the extension to .kepub.epub when sending it to your Kobo.

As mentioned above, generate a .kepub using kepubify and set kepub above epub in the files to send to your Kobo. I do this with the few books I want in kepub but I am using the KoboTouch driver.

That is correct. OTOH, you mentioned that you had also tried the KoboTouch driver which will not convert to kepub.

OTOH, I am no longer going to respond in this thread. I finally looked at the book in your download link, it is a copyrighted book and a conversion from azw3 to epub using calibre's conversion. Sorry but that tells me that book is a pirated copy and as such, I'm outta here. I had originally thought that you had purchased the book, downloaded it and converted to ePub but turns out that was a vain hope.

We need more information such as what computer and what OS.

It looks like the eBook is corrupt. That can happen if you have a MAC and use Safari to download an ePub as Safari is set to automatically uncompress a ZIP file which it what an ePub is.

Well that sorta means
1)the 'book' (zip layout) was not created properly
2)something messed with the book along the way and broke it
