There is a confusion somewhere. You have (had) a running Moodle installation. In that server you find a directory 'moodle' with no config.php. But there is a config.php in a the directory 'httpdocs'? I tend to say that 'httpdocs' directory _is_ the "moodle" directory. This time "moodle" is meant as a name, a reference to the directory where the Moodle code is.
To check its correctness, create a file test.html with some simple HTML (or even text) in the httpdocs directory and visit http://example.com/test.html in you browser - replace http://example.com with the URL of your Moodle site. If the browser shows you the content of your test.html, then 'httpdocs' is you "moodle" directory!
