If 'TasksDir' key is not defined in the [Settings] section in QPR_Clients.ini, predefined settings files are searched from the "C:\ProgramData\QPR Software\QPR 2019\2019.1\Clients\PGIntegrationTasks" directory. If the TasksDir is defined, task files are searched from there and listed in the XML Wizard's predefined settings list window.
Each application defines its own XML system task file extension. In QPR Modeling Client the extension is '.pgt'.
