What is OPF file?

The Open Packaging Format or OPF file extension is a typical file format that stores data regarding the specific e-book. The stored data can include the identity of the book, creator’s name, language, and the title of the e-book. All the OPF files are coded in XML. These files are a part of EPUB achieve. Opening an .OPF file would not be possible without a separate NCX XML file. That additional file stores the table of the content for the specific e-book and that’s why NCX XML file is needed to open the OPF files. The main purpose of creating OPF files is storing all the details regarding the e-books.
