[Super1Windcloud]

C:\Users\superuse\AppData\Local\fnm_multishells , it's all symbolic link , and I could open the every folder for corresponding Node version, but I didn't download so many Node version , this is why ?

multishells are the mechanism of how we can support a different Node.js version per shell session (so every Terminal tab you run can run a different version). They're practically free in terms of storage and they're an implementation detail.
