* <fn1> has to be valid and <fn2> may be NULL. If both pointers are
* non-NULL then the file is moved, otherwise it is deleted. The
* entry of the registrykey is always appended with two zero
* terminated strings. If <fn2> is NULL then the second entry is
* simply a single 0-byte. Otherwise the second filename goes
* there. The entries are prepended with \??\ before the path and the
* second filename gets also a '!' as the first character if
* MOVEFILE_REPLACE_EXISTING is set. After the final string another
* 0-byte follows to indicate the end of the strings.
* i.e.:
* \??\D:\test\file1[0]
* !\??\D:\test\file1_renamed[0]
* \??\D:\Test|delete[0]
* [0] <- file is to be deleted, second string empty

* !\??\D:\test\file2_renamed[0]
