What are Data Files?

The Data File format is used to store any data other than executable code - eg. a file that can be viewed but not executed. It differs from a "program file" in the fact that it does not contain a set of instructions for the computer (a code or a script) to follow. Furthermore, although commonly confused as a data file, "configuration files" (files that define the structure of an application or operating system) are also not classified as data files.

Data Files are the most common type of files used by a computer and are normally stored in a binary format, although some data files may also be stored in the form of text.
