Oh, I have hidden files shown, have for years. I mean I do not have a file by that specific name. The closest is in my extracted 4.11 folder, in the driver/9X_Inf/B_19048 folder, is things like atio9xxx and ati3duag (no file extensions, even clipped ones). I don't know if that's the DirectX9 folder or not, but the Driver folder itself has even less in it.
