For ftp, Yes. Just request a URL of the directory with a trailing backslash,
or use the CURLOPT_DIRLISTONLY option.

There is no standard way of requesting the list be sorted, and no standard
format for the directory listing, either. The only reliable way to do it is to
request a list of files only, then request the date for each of them in turn.
But, if you only care about certain servers, you can make some assumptions and
use nonstandard extensions to do it more quickly.
