* 1) WORD constant: zero (not validated by Windows)
* 2) length of the path string ("\0" included)
* 3) path string type A
* 4) Unknown WORD value: Frequently 0xFFFF, but not always. If set very large,
* Windows returns E_OUTOFMEMORY
* 5) WORD Constant: 0xDEAD (not validated by Windows)
* 6) five DWORD constant: zero (not validated by Windows)
* 7) If we're only writing the multibyte version,
* write a zero DWORD and finish.
*
* 8) DWORD: double-length of the path string type W ("\0" not
* included)
* 9) WORD constant: 0x3
* 10) filePath unicode string.
