No, I did not check the root of my drive, but can you explain how to do that as well?
look at this from your code above
set %rail_filename c:\noobiesrail.txt
I have no clue how to use this program but this either saves or reads a file in the root directory of your C drive.
so
right click on windows start button (lower left hand corner of your taskbar)
select open windows explorer
go down on left to local disk (c:)
click on on right should be all the files and folders in root directory of C drive
