LWSDebugOut.txt is a logitech file that captures errors. In my case 1.8GB of errors. This is because a new error record is appended every 5 seconds that the webcam is not connected.
The file is ok to delete. Better yet, Windows 10 can control the camera, so might as well uninstall the program.
- deleted, made read only, and stopped its insatiable growth desires at 8K.-
