I don't think that I am. But many applications refuse to even open a file without a "proper" extension regardless of the content, so sometimes all that is needed to go from not working to working is to rename the file. For example, unzip works just fine on files with the extension epub, but many applications do not. Absent your answer below, I would not know which camp the Voyage software is in, which is not necessarily the same as previous Kindles.

Thanks!

But just to clear, a Voyage will use a prc dictionary with extension prc with all Voyage dictionary features?

I am under the impression that the mobi standard is a proper superset of prc and azw a proper superset of mobi, but do not know what dictionary enhancements have been added as the file formats have evolved.

Because there are too many separate things that can go wrong and I would not be able to tell which one. For example, your next statement.

So I need to change the language code of the dictionary to English?

Can you point me to instructions or a tutorial?
