A CBR file is a compressed set of .JPEG, .PNG, or static .GIF images saved in a single .RAR archive with the ".cbr" extension. It contains pages that are automatically ordered and can be presented one or two at a time. The file is used for storing and displaying comic books or other collections of pages.
A file decompression utility that supports the RAR format may be able to decompress CBR files and extract the images. However, they will not be displayed in a book format and will not necessarily be in the correct order.
NOTE: The Komik Reader application for Android is available for free or purchase.
