Data Files

Data files are the most common type of computer files. They may be installed with applications or created by users. Most data files are saved in a binary format, though some store data as plain text. Examples of data files include libraries, project files, and saved documents.

NOTE: The Data Files category encompasses other more specific categories. File types that do not fit within these subcategories are placed in this category.

Common data file extensions include .DAT, .XML, and .VCF.
