Error in file upload

Hi all, I get the following error message:
Could not find file 'C:\CHURCHROOF - CRIME live 150110.xlsx'.
 
When running the following code:
 

  if (FileUpLoad1.HasFile)
            {
                string serverpath = "\\\\server1\\Temp\\ ";
         
                 //top.window.close();
                string filepath = FileUpLoad1.PostedFile.FileName;
                string filename = FileUpLoad1.FileName;
         &nbs ...
