Convert ORB to PDF

Unfortunately, there doesn't seem to exist any way how you can directly convert ORB ebooks to PDF format (or anything else). Nevertheless, you can use the following workaround to overcome this. First thing you have to do is to rename your .orb file as .zip file and extract the content using any ZIP supporting file archiver. This will give you several files including Flash SWF files for individual pages that have the GAU extension. Rename them all from GAU to SWF. Now what you need to do is to convert those individual SWF files to PDF format using any of the available swf to pdf converters. Some users also report that Adobe Acrobat is probably best choice, because it can also merge PDF pages to a single document.
