How do you guys manage your add-ons? I have a ton of add-ons that aren't from the Daz store and look like picrel so I manually dragged them into my install directory and now I don't know how to cleanly uninstall anything.

At this point I have so many outfits/addons I've only tried once that I want to find a way to cleanly install/uninstall 3rd party content and then start a fresh Daz installation.
