The Open Packaging Format (OPF) is a critical component in the EPUB digital publishing standard, specifically designed for eBooks. OPF files serve as a manifest that organizes and structures the contents of an EPUB file, including metadata, the reading order, and resource files. This standard, introduced by the International Digital Publishing Forum (IDPF) in 2007, aimed to streamline the publication and distribution of eBooks, ensuring compatibility across various devices and reading software. The OPF's primary purpose is to enhance the accessibility and interoperability of digital content within the rapidly evolving landscape of electronic publishing.
The PMLZ file extension stands for Zipped Palm Markup Language, developed by Palm Inc. It is a compressed archive containing one or more Palm Markup Language (PML) files, used to create eBooks in the Palm Database (PDB) format for Palm PDAs. With the decline in popularity of Palm devices, PMLZ files have become less common. Users can open PMLZ files using zip-decompression utilities like 7-Zip.
