The .kepub.epub and .epub extensions are used to decide which renderer to use. .epub uses the Adobe RMSDK renderer while .kepub.epub uses a webkit based renderer. Basically, you need to know which renderer to use before opening the ebook and the filename makes for very simple and fast code.

If you look in the library view, you'll see EPUB or KOBO EPUB. When reading, if you tap the middle of the screen, you'll notice a bar graph looking icon between the As and gear wheel icons. If you tap on an image, you'll get the 4 headed arrow to allow zooming, rotating, etc. the image. I've found that to be of little use since very few images in commercial ebooks have the resolution to make it worth zooming the image. I also prefer the RMSDK's font handling but that is likely only of interest to my fellow typography geeks.

The basic change in kepubs are not visible in other renderers so you would see no difference in how KOReader rendered the ebook.[/LIST]
