There are several ways to approach managing mods--and we each gravitate to the one that works best for us, hopefully. I have a folder called "Downloaded Mods" where I keep a copy of every version of every mod I have ever downloaded (call me a mod hoarder!) each in its own folder, because updated mod .pkm files often have the same name as older versions. Then, between games I copy the ones I want to use to windata and erase the ModEnabled_ and ModIndex_ keys from my Banished registry. This latter habit got started in the early days of modding when things were not always stable. I don't recommend it to those who are uncomfortable mucking around in the registry, and I always remind myself how little I know so I don't go doing dangerous stuff. I like the idea of the Mod Manager, but old habits die hard.
