Intonation problem

[J.R.303]

Thanks for the advise Of course I tuned the open string and the 12th fret

Can you explain what FW stands for?
My father has tiny triangular files. I think they should work
You say that the distance between 1st fret and (open) string should be the same as the second fret when holding down the first fret. Right??

FW = FrankenWashie.
