This question already has an answer here:
I have been using windows for a long time. And now I have moved on to ubuntu (13.04). I am just 2 to 3 weeks old for ubuntu. I don't understand about the directories like /var , /home, /media etc. . . Can somebody relate all the ubuntu directories to windows directories. That might be so easy for a beginner like me to understand. To be more precise, I don't even know which directory behaves like C: and which one behaves like D: or E: or others. I don't know where to save which kind of docs.
