CB2 file format:

A file format defines how the data in the file is structured. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the CB2 files produces the following result:
