I have a lot of Rfactor 2 (my favourite sim) DLC and Workshop items on my hard drive but am now very low on space. I no longer use any of the Reiza Track pack or Reiza Car pack DLC and want to permanently delete both of them as they are using a lot of space but can't because when I do they get reinstalled again on start up. Is there any way around this? DLC can be deleted from other games on Steam. Hope someone can help thanks.
