SyncToy

Many of you might know this one already but some of you might not, there is an excellent little bit of Sync software out there and guess what it's free! Guess what else... Microsoft make it :) http://www.microsoft.com/windowsxp/using/digitalphotography/prophoto/synctoy.mspx No doubt there are others out there, I for one have used another that needs no install (and so is useful for bringing about on a keydrive), but this one is the current favourite.
