Electronic Publications are essentially a package that consists of XHTML, XML, and image files and is compressed to a ZIP archive. By default, NOV rich text view uses medium compression level when creating the EPUB package. The medium compression level is a nice compromise between speed and compression ratio. If you want to change the compression level of an EPUB package, you should pass a NEpubSaveSettings instance with the proper value set to its CompressionLevel to the Save method.

Saving an Electronic Publication with a different compression level	Copy Code
NEpubSaveSettings saveSettings = new NEpubSaveSettings(); saveSettings.CompressionLevel = ENCompressionLevel.BestCompression; m_RichTextView.SaveToFile(@"C:\MyBook.epub", new NEpubTextFormat(), saveSettings);
