What is a PML file?

Palm Markup Language (PML) is a proprietary tagging language developed by Peanut Press (later Palm Digital Media) for formatting electronic text destined for eReader devices. Analogous to Markdown or HTML, PML utilizes specific ASCII-based tags (e.g., p for paragraphs,  for bold) to define layout and styling. These source files are typically compiled into binary PDB containers before distribution, making raw PML files rare in end-user environments.

How to open a PML file

As a plain text format, raw PML files can be opened and edited with any standard text editor such as Microsoft Notepad, Apple TextEdit, or Sublime Text. However, to view the rendered eBook as intended, the file must be compiled or converted using tools like Calibre or the legacy Dropbook compiler.

What is an LRF file?

The LRF (Broad Band eBook) format is a deprecated proprietary eBook format developed by Sony for its PRS-500 and PRS-505 e-reader series. It is a binary format that utilizes a specific XML-based markup internally for layout rendering, supporting hard-coded pagination, vector images, and zlib compression. Unlike reflowable formats, LRF defines static page layouts, which can lead to scaling issues on displays with resolutions differing from the original Sony hardware specifications.

How to open an LRF file

Sony has abandoned LRF in favor of the EPUB standard, meaning modern devices do not support it natively. The most reliable method for opening LRF files on desktop systems is using Calibre or the Summoner application. For viewing on modern e-readers or tablets, conversion to EPUB or PDF via Calibre is the standard technical workflow.
