What is an LRF file

LRF files mostly belong to Reader by Sony. An LRF file contains an e-book saved in BBeB (BroadBand eBook) format. BBeB format was jointly developed by Sony and Canon. A single LRF e-book contains multiple XML documents comprising text, settings, formatting, and references to images that make up a book. Calibre e-book authoring software can create and render an LRF file. Another type of LRF file saves the recorded progress of a player in League of Legends video game. Data stored in this file allows players to replay their gameplay experience. LRF is also the filename extension of a custom-drawn font used by Line Rider video game.

LRF file format details:

The file format determines how the data is stored in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>.
