QCF format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. 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. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below you will find our evaluation of the QCF files:
