CBR file is an archive of files containing images that have been compressed using .RAR compression. It's used in comic books or paperback file formats, the image files contained in a CBR file can be of type GIF, JPEG and PNG.
The LRF format is a proprietary format developed by Sony in collaboration with Canon, as a document and text encoding standard for the Broad Band eBook file format. The format specifically targeted Sony portable eBook readers and was capable of encoding both text, pagination, and images. Being unencrypted, LRF encoded files do not enforce DRM. This is in contrast to the LRX format which is also part of the BBeB eBook file format which does support encryption for DRM files. The Sony eBook store announced in July 2010 a discontinuation of support for the LRF format in favor of the public and open EPUB format.

CBR files are mainly composed of a series of image files, usually in a particular sequence, in lossless or lossy compressions (PNG and JPEG respectively) and are archived as a single or a group of files. The extension name seen on CBR format shows the type of archive used, for example, the archive type 7z may be used to store .cb7 file extension. The file names are usually numbered from the lowest to the highest number (in an ascending order).
The LRF format is an XML derivative. It represents the compiled and compressed binary format of the BBeB file. The structure of an .lrf file included a header, an object stream, and an object index. Though the LRF format is a proprietary asset, many freely available programs are able to convert and or open LRF files for viewing.
