What are even talking about? What path, what file info? Forget about c:\*; there are no such paths accessible by a Web application. The question makes no sense. The download is way to usual operation; I'm just afraid you are not ready to get it as you have some impossible misconceptions; you cannot even explain the "problem".

When you say it can't find the file, what exception it is throwing?

Just for the record: to download a file, you can use either System.Net.WebClient or System.Net.HttpWebRequest (for more flexibility):
http://msdn.microsoft.com/en-us/library/system.net.webclient%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest%28v=vs.110%29.aspx[^].

Please read this documentation; everything is simple.

But please see my comment to the question. Your "difficulties" are absolutely unclear and probably even unrelated to the downloading "problem".

You can get the path by using the folllowing code

C#

string cvFilePath = Server.MapPath("~/uploads/1.jpg");
FileInfo fiCv = new FileInfo(cvFilePath);
