HTML Executable provides you with some pre-defined targets that you can use not only for hyperlinks: see http://www.htmlexe.com/help/externallinks.htm
_heopenit can be used for any document file like executable program files, text files, Microsoft Office® files, etc…
Example:
<a target="_heopenit" href="mydocument.docx">Open this Word document</a>
