You are not true, Albert. The files, at least with poppler, are opened with
sharing enabled, i.e.

  HANDLE handle = CreateFileA(fileName->getCString(),
                              GENERIC_READ,
-->                           FILE_SHARE_READ | FILE_SHARE_WRITE,
                              NULL,
                              OPEN_EXISTING,
                              FILE_ATTRIBUTE_NORMAL, NULL);

That means that other processes are allowed to read and even write to the same
file!
But we can probably do the same under windows with GetFileTime, using the
lpLastWriteTime parameter.
