The most typical type of computer file is the data file which includes libraries, project files, or saved documents. Data files can be established in downloading applications, or simply created by the user. Data files can be saved in a binary configuration or as plain text.
Data files comprise more categories than libraries, project files, or saved documents, however file types that don’t fit in these categories are still placed in the data file category. Popular data file extensions are .DAT, .PST, .PPS and .PDX.
