ZipFileToCreate = "c:\user\desktop\webservice\file.zip";

so, when i try to save this file it creates the folder for the path like user\desktop\webservice\file\

why is it so,
                            FileStream fs = new FileStream(ZipFileToCreate, FileMode.Open);
                            byte[] data = new Byte[fs.Length];
                            BinaryReader br = new BinaryReader(fs);
                            br.Read(data, 0, data.Length);
                            br.Close();
                            Response.Clear();
                            Response.ContentType = "application/x-zip-compressed";
                            Response.AppendHeader("Content-Disposition", "filename="
                            + Parameter + ".zip");
                            DeleteOldFiles();
                            Response.BinaryWrite(data);
