Why can't I open the Page folio or NTZ archive I downloaded from my web mail account?
If you are trying to download a Page Folio or NTZ file using Safari, ctrl-click on the link and select "Download linked file" in order to get the file correctly. Safari will attempt to de-compress gzipped data when downloading files by clicking directly on their links. This causes files to arrive corrupted and unable to be opened. The ctrl-click method overrides this behavior and delivers a valid file.
