Delete all Contacts, To Do, and Events in a Treo

I recently had a problem with my Treo 650 where all my To Do's, Contacts, and Calender events were duplicated multiple times.  I changed my Hotsync settings, so the desktop would overwrite the palm, but the duplicates still stayed.  I found this program called FileZ which will allow you to go into the palm and delete all these items without doing a hard reset.  Instructions can be found at this blog.
