If this is a windows application, and the file is already in the application exe directory, they you don't need to download it - the EXE can read the file, so it can either use File.Copy[^] to copy it to a new location, or read it as bytes, and write it back to it's new folder.

Why would you think of this as a download?

I want to display a file on click to view file. The user can have the folder with exe in any drive like c or D...How can I specify the file path.

Do you mean how do you get the user to specify the path to the file?

Yes exactly.

Open a file browser dialog:

SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "PDF Files (*.PDF) | *.PDF| All Files|*.*";
if (sfd.ShowDialog() == DialogResult.OK)
{
// Copy your file to sfd.FileName.
string s = sfd.FileName;
}

C#

private void DownloadFile()
       {

           wc.DownloadProgressChanged += WcOnDownloadProgressChanged;
           wc.DownloadFileCompleted += WcOnDownloadFileCompleted;
           string downloadUrl = ConfigurationSettings.AppSettings["fileDownloadPath"] ;


           wc.DownloadFileAsync(new Uri(downloadUrl), @"C:\\fileName" );
           handle.WaitOne(); // wait for the async event to complete

       }

       private void WcOnDownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
       {
           if (!e.Cancelled && e.Error == null)
           {
               //async download completed successfully

           }
           handle.Set(); // in both the case let the void main() know that async event had finished so that i can quit
       }

       private void WcOnDownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
       {
           // handle the progres in case of async
           //e.ProgressPercentage

       }
       private void butsync_Click(object sender, EventArgs e)
       {
           DownloadFile();
}
