You can empty the trace files in transaction code SM50. Go to Process > Trace > Reset > All Files or Work process files.
You can choose whether to reset all files or only work process files. All Files mean all dev* files on this server. They include the traces from the gateway, dispatcher, ICM, RFC, and so on, as well as the work process traces. After the trace files have been reset, the information contained in them is lost and cannot be retrieved.
