I hope this is a simple answer and I'm missing something.

I have found the example how to destroy all deleted files in a folder in the EPDM API Help (http://help.solidworks.com/2015/english/api/epdmapi/destroy_deleted_files_in_vault_example_vbnet.htm_)

What I can't seem to find is how to destroy a single file.  I would like to automate the process of destroying all "Private Files" users previously deleted but not files that have been previously checked in and assigned a workflow state they have deleted.
