how to programmatically attach a file through the attach outlook command line switch

Hello ALL!

I've got an outlook 2010 commandline switch question

I know command line switch /a "C:\dox.docx" attaches the file dox.docx to an email but:

how do make this switch attach the first file that meets a certain criteria e.g. I want to make it attach the first docx file that starts with a "D" on the C:\ drive without giving the switch a specific path to the file like say: /a "C:\dox.docx".

Thoughts?

Thanks helpful folks.
