I have no idea how to do that.

After spending hours copy pasting all those "converted" files back in their original folders and removing the old ones. Save to disk: Save only EPUB to disk in a single folder. It doesn't do what it says as it results in 3 file's per book to appear in that folder (cover.jpg, metadata.opf and the actual .epub file). Well it was rather challenging as the filenames aren't preserved trough this method. So that's rather messy now. Also some files got messes up I haven't checked all of them of course but what I did see was that some got extra pages inserted one even had all the images cut into horizontal section.

I also did some testing convert vs the editor's image compression. Well even though the convert method reduced 12GB to 1.8GB, the image compression method is even more efficient at least for the files that I tested, there was at least an extra 40% reduction and no messed up file names (and no other mess ups).

So PLEASE add bulk functionality to the editor's image compression function.
