How to get a huge file size

static bool GetFileSizeEx(LPCSTR Path, LARGE_INTEGER& Size)
{
    HANDLE hFile = CreateFile(Path, GENERIC_READ, FILE_SHARE_READ, 
        NULL, OPEN_EXISTING, 0, NULL);
    if (hFile == INVALID_HANDLE_VALUE)
        return(FALSE);
    Size.LowPart = GetFileSize(hFile, (PULONG)&Size.HighPart);
    CloseHandle(hFile);
    return(Size.LowPart != 0xFFFFFFFF || GetLastError() != NO_ERROR);
}
