new to programming, I am downloading software to help me create my program. I am told often check that the file is on your system path or add to system path.
I know how to change system path and how to add a new path.
What I don't understand is what goes on system path? how does it work? For example when I download programs why don't they end up in the program's file on my C drive why are they under my user name in a folder called downloads?
The programs I am working with are R and Weka, they are both used for data analysis. I have to download packages for each of these programs, these packages are like libraries so when it says make sure bla bla bla is on the system path does that mean the entire R program or that one piece that was downloaded its all confusing?
