They open in Preditor Editor.The files show the same as opening in notepad.
The machine parameters,at least with mine,,aren't to be messed with,except maybe a qualified technician.
If you were a qualified tech,,the numbers you see would probably make since.
Now there are other parameters on my machine that the user can change,but these are spelled out on screen.You either say yes or no,,or turn on or off.
My take on this.
