Slightly noob question I guess - but what is the right way? I learnt my way very well around the folder structure of rF1, but with this one I'm lost Is it just deleting the particular track (or mod) from your Packages folder? Or is there more to it?
If you remove the track/mod from Packages folder you dont uninstall it. To uninstall a track/mod you have to use the Mod Manager: right mouse click on the track/mod you want uninstall, then select "Uninstall". If you want to uninstall a component, for istance a track, uncheck "Show Mods Only", in the Options menu.
