Was wondering how can I have two folers so when I launch the Launcher from the non modded one, it launches that, cause it seems that Steam only wants to launch the the direct path

Have one folder named the default 'skyrim' and the other something else (ex: skyrim2), when you want to play using 'skyrim2' simply name 'skyrim' something else and name 'skyrim2' 'skyrim', that's how I do it atleast.

Depending on what type of mods you're trying to not play with, you might just need multiple /data folders, renaming them as described above. Though when I was doing that I had a mod manager that let you import/export load orders from/to text files, not sure if there's anything available right now that will let you do that.

I did this in Morrowind and Oblivion. It works well. I'm sure I'll be doing it in Skyrim as well, once a lot of CK-made mods start coming out.
