Description A .cbr file is a compressed file that allows a set of comic book images to be stored. These images can be ordered and the format in which they are displayed can be altered to allow two images to be viewed side by side, in the same way as a double page spread would occur. AZW3 - Kindle Format 8 (KF8) is Amazon's newer version of AZW. It supports HTML5 and CSS3 which were not supported through the standard AZW format. It has a number of other formatting options and is used by Amazon for all new Amazon eBooks. It is supported by fourth-generation Kindle devices running firmware version 4.1.0 or later and the Kindle Fire device.
Technical details A .cbr file is actually just a .rar file with an amended file extension. What makes a .cbr file different is that it can be opened directly by comic book viewer applications without a requirement to decompress it first. The user can also associate the file extension with a Comic Book Viewer application. Typical image formats are allowed for a .cbr file such as JPEG, GIFF, TIFF and PNG. KF8 (also called AZW3) is essentially a compiled ePub that has utlises a Palm database and Amazon's DRM scheme. It targets ePub 3 version support but existing ePub can also be used. The internal format has been decoded using mobi_unpack. The basic format remains as a PDB file similar in structure to a MOBI. More oftent than not a KF8 file will contain both a MOBI file at the beginning and the newer KF8 version of ePub later.
