What is the best way to un/reinstall Auto1111 without losing all my models and extensions? (because those models are kind of a pain in the ass to download because they take FOREVER)

Like many people, I loaded Automatic1111 months ago when it was new. Over time I kept adding various extensions or models I wanted to use.

There were several things I couldn't figure out how to load or make work at all (sorry, I'm kind of a Noob to all this commandprompt github stuff).

Anyway, as I loaded more stuff, various ones would stop working. Tried to keep python and A1111 updated as much as possible. Sure some stuff was giving me errors, but at least base-stable diffusion would still work.....

Well, I just tried to load SDXL, which (according to Aientrepreneur) I allegedly just needed to load into my A1111 models folder, which I did.

Now everything gives me errors, sometimes different ones, (I can get more specific about this if someone wants to hang out with me a minute and figure all this out). Google searches and ChatGPT haven't really been able to help me either. Face it. As great as these AI tools are, they aren't really "there" yet, I need a human who knows what they're doing to talk to me as an individual (because I've tried some youtube tutorials too, and if my problem isnt covered by their video, then I'm SOL).

I apologize again for being a noob. I know some communities really take offense to noobs.
