Something that works but that I dont like&nbsp; is&nbsp; after saving&nbsp; the zip to create a new zip file by reading the just saved file, then update and then save again.&nbsp;</p>\r\n<p>Any help will be greatly appreciated.</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>\r\n<p>&nbsp;</p>",
