Hey guys, I'm new to modding Skyrim. And I think I have it figured out for the most part, and the Nexus Mod Manager streamlines a lot of things. But when you try to add two mods that may conflict it usually brings up "No, No to all, No to Folder, No to Mod. Yes, Yes to Folder, Yes to Mod, Yes to All." What exactly do each of these options do, and is it possible to run two mods even if they are conflicting in some way? Thanks! I didn't really know how to phrase this question when searching for the topic so I just made my own.
