redo epub to epub - don't use original-epub
i want to re-convert some epub books in order to use the CSS filter options.
I don't however want to convert from the original-epub files because if I do that I will lose recent edits made to the epub versions. i want to convert from epub to epub, as if the original-epub format was not present, and not to overwrite that original-epub format file at all
so is there any way to run a bulk epub to epub conversion with a setting that says don't use the original-epub files
otherwise its a complicated fudge. I'd need to go into DOS, rename all instances of that extension to fool calibre, then rename it back again afterwards ?
