OP I think the word "download" doesn't mean what you think it means. Do you mean "import"?
I agree with the previous replies that what you wrote doesn't make much sense.
Also, in English, "What part of...don't you understand?" is a pretty confrontational and obnoxious question to pose toward people who are trying to help you. In English, it implies that you said something very self-explanatory that the person asking for clarification is demonstrating themselves to be too stupid to understand. I'm sure that you, as the person asking other people to figure out how to do something you can't figure out how to do, didn't mean it that way.
