(How) is it possible to delete all CTA recordings on an IPC at once? The app slows down noticeable if many (big) records are present so I would like to remove all recordings at once. If it is possible to clear the complete database (by hand) that would also be an option I would consider.
This option is not yet available. However, it is possible to set an automatic deletion of the data record in the global parameters of the service (C:\OpconApp\Cta\GlobalSettings.xml). There is an entry which is named AutoExportFileDeleteTimespan. (Sorry, unfortunately it is currently not possible to upload pictures).
