It would be interesting if one of the people that was having to rename the files with 7 characters or less would reinstall and set both paths to C:\Games\rFactor2 or something like that to see if they can then use more characters. This would give us more information on the max path limit for the game.
The above worked for me, I have W7 64bit What about the helmet file? I cannot get it to work perhaps because it has to many characters also. How will this be placed?
I created some ALT that are too long in their names, and are not visisble I redid this mod and it goes well
