You have to use FileUpload.HasFile Property.
 
Only if it has file, then get the path else dont.
 
Sample code.
 
void btnSave_Click(object sender, EventArgs e)
{
  if (fileupload.HasFile)
    {
      fileupload.SaveAs(Server.MapPath(FileVirtualPath + fileupload.FileName));
     }
  Save();
}

The fileupload control has a HasFile property. do all your fileupload related logic after checking for HasFile
 
if(MyFileUpload.HasFile)
{
  //all file upload related code here
}
else
{
  //no issues, go ahead
}
