Both of my servers are in seperate folders, fhro is in the Gravity folder and llro has it's own seperate folder.
The sdata file is present in my Gravity folder and it's data.ini file looks the way you say it should.
As for llro seeing as it uses it's own client it has sdata built into it's own .grf file and because of that, has a data.ini file that looks different from your example.
