I know what the root directory is, of course, but it is very difficult for me to explain to people what it is. I wrote a Nintendo DS application that requires the folder to be copied to the root directory of your memory card, and I often receive emails from people who copied them in the wrong place and don’t understand what the root directory is. I do not think that they understand that the root directory can be considered as a directory or "folder".
What is the best way to explain this to people?
