I can't add all the files at the same time and I might need to open the file up a few times and add more files until completion.</p>\r\n<p>Everything seems to work ok if I use 1 zip but when I try and make use of spanning I seem to run into problems.</p>\r\n<p>&nbsp;</p>\r\n<p>Cheers,</p>\r\n<p>John</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>",
