Hi,
I think you are doing good ,but you need to change some little bit of code,

Ok
Then Pass the file path in "string fileName = "foldername\ManualEntry.XLS";

You need to save the image path in database and then when you want to download the file pass the id and get the full path from database and pass the path as file name
