How to stop converting to DOCX?

[edent]

I'm connecting KOReader (2021.08), running on a LikeBook Ares, to Calibre (5.25.0) via WiFi. Whenever I send an AWZ3 book to main memory, it converts to DOCX. I want it to automatically convert to EPUB instead.

I tried removing the DOCX plugin, but it can't be removed or disabled.

I've set

restrict_output_formats = ['EPUB', 'AZW3']

and restarted. But books still get converted.

Under Behaviour - the preferred output format is EPUB.

If I choose "Send specific format to device", DOCX is the default.

Under "Configure This Device" there are no options for preferred file format.

Is there any way I can remove DOCX completely - or set EPUB as my default for sending to a wireless device?

Thanks!

How are you connecting via WiFi? Most wifi connections are pull based via the content server. Is this a special client on the device that uses the same wireless protocol as calibre companion?

It is using the smart app driver, like CC.

Does the list of supported formats sent to calibre imply an order?. In that case I'm afraid that docx takes precendence over epub: https://github.com/koreader/koreader...extensions.lua

There's no gui to change the list of supported files on KOReader, but OP can create its own set of supported extensions to send to the server.

Just create a file named calibre-extensions.lua in dataDir (that would be /sdcard/koreader on most android devices) with the desired extensions, like:

return {
    "epub",
    "fb2",
    "pdf",
}

Save it and restart the client/program.

I'm using https://koreader.rocks/ - an Android app. I start the content server in Calibre, and then in KOReader connect to it. It shows up as "KOReader Ares" and I can "push" books from Calibre to my eReader.

Does that help?

I don't know too much about it - but there's documentation at https://koreader.rocks/doc/topics/README.md.html

Yes, calibre assumes that the list is in desired order. If no format on the list exists then calibre converts the book to the first format.

Thanks for the hints, as always

Then I'm going to assume that calibre omits conversion to 'azw', 'cbz', 'chm', 'djv', 'djvu', 'doc', as all of them have higher priority than 'docx'?

SMART_DEV (  38.02:  0.000) open selected formats ['azw', 'cbz', 'chm', 'djv', 'djvu', 'doc', 'docx', 'epub', 'fb2', 'htm', 'html', 'md', 'mobi', 'pdb', 'pdf', 'prc', 'rtf', 'txt', 'xhtml', 'xps', 'zip']

none of those are formats calibre converts to.
