Thanks for providing the domain name (it helps). From my computer, that domain name does not yet resolve via DNS. If you created it , or changed the nameservers for it, recently, don't forget that it can take from a several minutes up to three days for the DNS updates to be completed around the internet.
It is not that your domain is not showing the files as much as it is that your domain is not yet reachable via a browser due to DNS updating.
Not really...I don't know anything about that either . If you mean to type ".tld" than I can clarify: .tld is just used to indicate "Top Level Domain", as in .com, .net, .org, etc.. It is ususally used in conjuction with "youdomainname" (yourdomainname.tld) to indicate a domain of the form "whatever your domain name is, followed by a "dot", followed by whatever Top Level Domain your domain name uses" .
