No file after completing by Ctrl+C

[s-lexx]

Hi, I set up the Livox-Horizon-LOAM according to the instructions posted here https://github.com/Livox-SDK/livox_horizon_loam. running commands: roslaunch livox_ros_driver livox_lidar_msg.launch roslaunch loam_horizon loam_livox_horizon.launch execution and visualization via RVIZ is underway. But after the algorithm completes, the *.lvx file is not generated. Where should the file be saved by default? What could be the problem?
