I've just updated my DCS install, and noticed that of the 82.8 GB used, 33.3 GB is in my Mods folder. If I installed any of that myself, it must have been done some time ago, and I don't think I need it now, since I can't remember what any of it does. Is it safe to delete the content of the Mods folder and its subfolders, or is there stuff in there that is necessary for the sim to work?
