As I downloaded more and more mods I found I was driving myself nuts trying to keep them all straight. To deal with the anarchy, I created a new folder under my Banished folder called Downloaded Mods. The game completely ignores this folder. I download all mod .zip and .rar files to that folder and unzip them there into a folder with the mod name and version number. That helps me prevent mod chaos. When I'm ready to start a new map with a different set of mods, I can remove old mods and copy new mods into windata quite easily. Note: I don't move files because that erases them in the original folder. I copy them and always make sure that I maintain the copy in the original folder.
