Information about MOBI and LRF file formats

🔸 File format MOBI LRF
🔸 Full name MOBI - Mobipocket Sony Portable Reader File
🔸 File extension .mobi, .prc .lrf
🔸 MIME type application/x-mobipocket-ebook application/x-sony-bbeb
🔸 Developed by Mobipocket SA Sony
🔸 Type of format Ebook file format eBook File
🔸 Description The MOBI file extension was created in 2000 by Mobipocket. This company produced Mobipocket Reader applications for computers and smartphones. In 2005, Amazon bought Mobipocket. As a result, MOBI files are identical to Amazon's AZW format for Kindle devices. The LRF file type is a proprietary file type created by Sony 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.
🔸 Technical details The Mobipocket ebook 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 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. LRF files are compressed, unencrypted files that may contain text and images featuring Sony's DRM protection. In addition, an LRF file may contain one or many LRS files which contain XML structuring.
