..or talented enough to write in place?
Something like a chapter from "Computers for beginners".
What is a directory, a file, what is
\ and so on
What is absolute, relative paths and what is working directory.
What is the difference between HTTP resource and a file and where do they meet. What is a root and what is the difference between filesystem root and a web-server root.
We desperately need such a link for every filesystem-related question.
Especially because most of ones who try to answer, do not understand it either.
