OBK file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be determined based on the file extension and the signature (the first few characters of a file). File extension, signature and file format must match; otherwise errors will occur when the file is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the OBK files is as follows:

As a file extension, OBK isn't very common and includes different formats for the applicable programs. But the following two file formats are common:
