Drivers and vehicles can not be removed from the seminar schedule because you have to keep monitoring the data according to regulations. If an employee leaves your company and you no longer wish to monitor this data automatically just simply move the driver or vehicle data from the archive to another location or storage medium. The data is then no longer included in the schedule. To get to the storage path of your files, click in the software "File Archive" and then the "Open Folder" button. To delete or move the files / directory, type in the file archive in search of the top left of the name of the driver / vehicle, which is excreted. Now just check the entry below to select the appropriate action, eg: "Save as" and or "delete".
