| Description | The LRF file type is a proprietary file type created by Sony for use with Sony branded eBook readers. LRF, along with LRS and LRX made up the now defunct BroadBand eBook or BBeB. The file type was discontinued in 2010 with the Sony eBook store selling in the ePUB format. | Mobipocket SA is a French company incorporated in March 2000 that created the .mobi e-book file format and produces the Mobipocket Reader software for mobile phones, personal digital assistants (PDA) and desktop operating systems. |
| Technical details | LRF files are compressed, unencrypted files that may contain text and images featuring Sony's DRM protection. An LRF file may contain one or many LRS files which contain XML structuring. | The Mobipocket e-book format is based on the Open eBook standard using XHTML and can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases. The Amazon Kindle's AZW format is basically just the Mobipocket format with a slightly different serial number scheme, and .prc publications can be read directly on the Kindle. The Kindle AZW format also lacks some Mobipocket features such as JavaScript. |
