    • /components/namespace/component name/ - catalog containing components 2.0 of the module;

    • index.php - file containing module description;
    • version.php - file with module version. Version cannot be null.
  • include.php - this file is connected when the module is connected in a code; all files containing libraries of functions and module classes must be located here;
  • default_option.php - contains an array named $ID module_default_option where default values are set for module parameters.

    Note: If the module name contains a dot (e.g., mycompany.forum) in the name of a variable, the dot will be replaced with the underscore character.

  • options.php - this file is connected on the setup page of module parameters in the administrative menu Settings;
  • prolog.php - this file can be connected in all administrative scripts of the module. Normally the constant ADMIN_MODULE_NAME (module identifier) which is used in the control panel is determined here.
  • .settings.php - module settings file, describing module settings that can be read via \Bitrix\Main\Config\Configuration::getInstance($module).
