Hi Daniel,

I am sorry for my delay (I am also working in another project :( ). I am
sure it is not libcurl's fault but mine, here is my code (I hope you
understand what I am doing). Thank you very much for your time

Guido.

dwLocalFileSize, DWORD *pdwRemoteFileSize)
{
    struct curl_slist *headerlist = NULL;
    char cmd[_MAX_FNAME + 10];
    CURLcode res;

    *pdwRemoteFileSize = 0;

    sprintf (cmd, "SIZE %s", file_name);
    headerlist = curl_slist_append (headerlist, cmd);

    curl_easy_setopt (curl, CURLOPT_VERBOSE, TRUE);
    curl_easy_setopt (curl, CURLOPT_DEBUGFUNCTION, MyDebug);
    curl_easy_setopt (curl, CURLOPT_DEBUGDATA, pdwFileSize);

    curl_easy_setopt (curl, CURLOPT_URL, url);

    curl_easy_setopt(curl, CURLOPT_POSTQUOTE, headerlist);

    res = curl_easy_perform (curl);

        }
    }
}

datalen, void *pdwRemoteFileSize)
