How would the command line tool work if it didn't?

1. set CURLOPT_VERBOSE to 1L first to see if it tells you anything interesting

2. check/print the return code from curl_easy_perform() as it is probably
useful

The URL you're working with looks weird: "file:////<ip_address>/ShareDrive/"

The format is "file://[host]/path" and the only [host] that curl accepts is
one of "" (nothing), "localhost" or "127.0.0.1". The file:// URL format
doesn't really specify how to connect to another host.
