Renaming docs converted to kepub

[bob.f]

Hi,

Let me preface this by saying that the inbuilt ability of Calibre to convert to kepub on the fly is of no use to me. I use a wireless connection to transfer my books and something no-one ever mentions is that this conversion does not work over wifi.

I am considering changing the default book format in my Calibre library from epub to kepub. I notice though that when Calibre converts to kepub, the resulting file is a <title>.kepub, whereas the files on my Kobo tend to be <title>.kepub.epub.

Is there a way to instruct Calibre to change the default extension used when converting to kepub?

no formats in calibre are identified by file extensions, so kepub must always have a kepub file extension while in the calibre library.

Thanks Kovid.
