Capture Uri of Extract Markup Zip Folder?

Hello,

I would like to be able to reliably capture the uri of the temp file created when the Extract Markup functionality of a Silverlight 1.9 viewer is called via a RunExternalCommand activity within workflow.

My goal being to then use a download activity to retrieve the zip file and then package it as an attachement for a SendMail activity.

Any help would be great.

Thanks,

Matthew
