* non-NULL then the file is moved, otherwise it is deleted. 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
