What is a LRF file?

LRF files have multiple uses, and Sony Portable E-book Reader Unencrypted Book is one of them. Read more about the other uses further down the page.

Sony Portable E-book Reader Unencrypted Book

These files are electronic books in Broad Band eBook (BBeb) format - a proprietary eBook format developed by Sony and Canon for portable Sony e-book reading devices.

Unencrypted e-books in this format are saved with the .LRF file extension, whereas encrypted books are saved with the .LRX file extension. Encrypted books are protected with a Digital Rights Management (DRM) system, so only users who purchased the book can read it.

The Sony e-book store switched from the BBeB file format to the more common EPUB file format in 2010.
