FlipViewer is a content viewing and publishing application that allows users to create and save digital magazines, catalogs, and other forms of eBooks. The app saves these eBooks, known as FlipBooks, in the OEB Package Format (OPF). These packages consist of an OPF file and imported content files (such as images).
Alternatively, users can save FlipBooks in the .OPZ format. An OPZ file is a single, zipped file that includes a FlipBook's OPF file and all referenced content files.
