CF file format:

To view or edit CF files you need to know the file format, because it determines how the data in this file is stored. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening.

25% of all CF files store the data in the config file format. A configuration file is used by computer software to store settings. It consists of a text-based content with a structure and syntax comprising key–value pairs for properties, and sections that organize the properties. The contents of these files can even be read by a human. The files are on average 720 bytes in size and range from 640 bytes to 1 KB. This file type is based on cutting-edge technology. Several words can almost always be found in the files, e.g. ; *DO NOT EDIT* this file unless you are understanding what you are doing, ; ==========, ; FYI and ; Each line consists of NAME="VALUE" p. Some examples of file names are engine.cf or Game.cf.
10% of all CF files use the same file format, which can be identified by the letters "ÿÿÿ" at the beginning. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. A typical file size is 59 MB. The following filename is common: 1Cv8.cf.
