How do I delete a local file in wpdm without checking it in

Opened/checked an assembly out and it copied all the files (children...) out to my local drive.  When I opened the file I did not take ownership and it was read only.  Now that I'm done using this upper level assemebly I want to, not check it in, but shut it down and have all the associated local files removed.  Anyone have any ideas??
