Every now and then you run into a new tool that you should have had for a long time.  I recently showed a co-worker DebugView from SysInternals.  This is great for capturing System.Debug.WriteLine messages even better Log4NET trace messages.  But I found one today: RoboCopy part of the Resource Kit!  This is great for a primitive backup of directories because it only copies changed files!  Another NEW TOOL I use regularly is LogParser, it allows you to run SQL queries against a variety of Microsoft log files.
