..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
edit To ones who closed: you guys are not right.
This question is related to computer hardware or computer software in general, yes.
But those your "enthusiasts" who asks their silly programming-related questions here, do not have this "general software" knowledge.
It's impossible to answer numerous questions like this one without such an article. It is exactly programming related question and nothing else.
