The ETS_snowfiles.rar file you have requested: Modifications / ETS Snow Files - 258.5kb is not available. Perhaps try browsing all files for the game Euro Truck Simulator Gold and upload any files you want to share or are missing. This is the only information we could locate:
This is a couple of textures adapted from ALH to ETS. They will cover the asphalt with snow, but only to roads and hi-ways. I still haven't figured out how to add that to prefabs and other likes. Snow files to use with ETS map editor.
