The structured file is a one of the most popular data format. Messages, logs, configuration files have structure but unlike database tables it is not tabular. Usually we can define template with changeable data items in some positions like "First Name" or "Subject" in the e-message or date and time in the log file. DTM File Factory was designed to generate data files by template. The user allowed to provide template and set data generation rules for changeable data items.
