Run site from an external or network drive?

@clay could you please explain/demonstrate exactly what I need to do to have my files (also my database?) on my network drive?

I saw this comment from Using Symlinks with local - #4 by jeffcleverley - Support - Local Community

But then I didn’t know which things to do here: Image 2018-02-15 at 10.30.4...

And he mentioned symlink, but you said that doesn’t work.

Thanks for the help.
