Select ASP.Net WebSite, and the following files will be created as shown below.
Intranet users: FYI, the virtual path is http://manas6/aspnet.35/mm.richcont2/ and pull path is C:\inetpub\wwwroot\aspnet.35\mm.richcont2

There was an error, as shown below due this faulty code

try
{
//FileUpload1.SaveAs("C:\\Uploads\\" + FileUpload1.FileName);
String str_path = "-/upload/" + FileUpload1.FileName;
// FileUpload1.SaveAs(MapPath(str_path) + FileUpload1.FileName);
FileUpload1.SaveAs(MapPath(str_path));

Corrected, if you are using IIS, and may face this error show below; meaning you can't access this folder due to security setup.

try
{
//FileUpload1.SaveAs("C:\\Uploads\\" + FileUpload1.FileName);
String str_path = "~/upload/" + FileUpload1.FileName;
// FileUpload1.SaveAs(MapPath(str_path) + FileUpload1.FileName);
FileUpload1.SaveAs(MapPath(str_path));
