Easiest way to sync two folders?

Need some automated utility that'll automatically synchronise the documents folder on my HDD with a USB drive and an external HDD every time I plug them in, automatically copying the most recent version of each file to the other medium.

If I need to write a batch file to do this, what can I do with it that I can't do with xcopy?

Right, downloaded Synctoy and read through the white paper, but it doesn't seem to list the command line parameters for it in there. Where can I find them, so I can make an appropriate batch file and schedule it to run at intervals?

I still run an xcopy commant in a batch file to copy new documents to my backup partition twice a day, but that only needs to be one-way, I need it to automatically copy new files to and from the external devices, preferably automatically the first time I plug them in.

SyncToy seems to be the only suggestion that'll sync folders both ways. Sone's suggestion to set up the USB drive's autorun.inf to run SyncToy on plugin is probably the best way, but I still haven't found the command line switches for it anywhere - it just opens up a wizard whenever I run it. I'll run it manually if I have to, but would be cool to have it sync anything I plug in automatically! (This is why I'm a sad nerd, I spend more time setting up my computer to do something automatically than it would take me to just do it myself!

)

Would SyncToy still work if the drive letter assignments change? The USB stick doesn't always get the same drive letter depending on what else I have plugged in. Would it also sync documents stored on my smartphone's memory, or is it only ActiveSync that can do that?
