Sync folders on your PC with your mobile storage device!

A new beta download from Micro$oft:
SyncToy for Windows XP

Would be really useful for PDAs, memory cards and USB thumbdrives. You can keep all the files on those stuff the same as the files on your harddrive by syncronization. Said to be a preview of a function in the next version of Windows (Vista), but what's important here is that it's really useful, wither it's a preview of what-so-ever.

I'm getting it now, really excited to give it a try.
