Calibre has stopped changing Epub to Kepub
I had a Forma and Calibre used to convert Epubs to Kepubs automatically when I transferred files.
I cannot remember how I made it do that.

I now have a Libra 2 and find that all the files being sent to it remain as Epubs

What has changed:

In order to make my Calibre 3.48 recognise the Libra 2, I installed plugin Kobotouch348 by David Forrester and disabled KobotouchExtended at the same time, as per the instructions

I would guess that this caused it, though I can't find a setting in it that mentions Kepub.

How can I make it convert automatically epub to kepub please?
I assume I could run a straight convert on each one from epub to kepub if I wanted to.

On a secondary note, since I hadn't noticed it was transferring files as epubs, and was happily reading away till I read a post on here and checked, I'm wondering if it's worth bothering and if I should just use epubs?

I can't for the life of me remember why I started it converting, but assume I read on Mobileread that it is a good thing to do

KoboTouchExtended is what converted ePub to KePub on the transfer to your Kobo. Disabling it stops that from happening.

Ah. Thank you Jon.
Since the instructions for Kobotouch348 include
Disable the KoboTouch and KoboToucExtended driver
it looks as though it's just the way it is then

That is correct. Using the Kobotouch348 driver doesn't allow using the extended driver. I was not able to work out how to load the drivers in the correct order for this to work.

You can convert manually. But, you can configure the driver to automatically run a conversion before sending the book. You will need to have the Kepub Output plugin installed and you should also have the Kepub Metadata Writer plugin installed. Then, in the driver configuration, in the formats list on the first tab, unselect epub and make sure kepub is selected and it is the first option. With that, calibre will convert any epub you have to kepub and then send it.

If you ask in the Kobo forum which is better, you will get lots of replies telling you that one of them is better and the other is rubbish. Epub has better typography, but, most of us don't care. Kepubs handle footnotes better, but, how many of your books use footnotes? I use both but the main reason I bother with kepub is that I like the chapter progress graphs.

It's personal. If you like one format, then read the books that way.

And Jon strikes again with his helpful post.

Thank you David for taking the time to reply so fully.

From what you say, I think I'll just stick with Epub as I don't use footnotes (and hadn't noticed the difference).

Epub to Kepub
Hi,
after the penultimate update of Caliber, I can't convert epub to kepub anymore.
I always get the same message: ModuleNotFoundError: No module named "PyQt4"
or
AttributeError: Metadata widget object has no attribute "opf_file.
what should I do? Thank you!

Download and install the KoboTouchExtended driver and use that. Disable the KoboTouch Driver as you won't need it. Witht he KoboTouchExtended driver, the ePub is converted to KePub on the fly and you don't end up with another eBook on your system.

Extended auto disables the Touch driver when active. The Kobo (PI) menu has a item that flips which to use. KISS

Yeah. I flip constantly between them, as I read epubs on the Libra and kepubs on the Sage.

The current KoboTouchExtended includes a way to have either ePub or KePub sent to your Kobo. I have a Y/N column and if it's Y, I get a KePub. Otherwise I get ePub.

This is the code that I use in the extended section.
Code:
program: 
	$#kepub == 'yes'

The problem with that is that I have mostly the same books on both, as I often switch between them reading the same book. Whether I send kepub or epub depends on which device is connected at the moment. I can't think of a way to populate a column based on such a setup...

There is a beta that should fix this in the thread for the Kepub Output plugin.

As a new Kobo user, I'd be interested to know what you base that on?

Why? It seems like a bit of work to switch like that.

Because epubs look visually better than kepubs, especially on a smaller screen, but kepubs are zippier and have image zooming. The Sage has a big enough screen that kepubs look pretty good on it too. On the Libra I still prefer epubs, solely because they look nicer.

I don't connect my readers to a computer often enough for the driver-flipping to bother me. I already have a thousand or so books on them, so I connect only when I really, really want something that isn't there already.
