What is an LRX file?
File used by the Sony Portable Reader, a mobile device that allows users to read eBooks; contains data for a Sony "BroadBand eBook" (BBeB), such as the images, text, and pagination data; saved in an encrypted binary file that includes a header, a specified number of objects, and an object index.
LRX and .LRF files comprise the two available BBeB book formats. While LRF files are unencrypted, LRX files are encrypted and are protected by DRM. DRM limits the number of devices that may use the same LRX file.
