SyncToy 1.4 PowerToy for Vista.

[anandk]

If you need to syncronise to something that's not supported, eg a digital camera, across folders, or even between different computers, then SyncToy 1.4, a PowerToy from Microsoft, which is Vista compatible, and will let you sync a folder to a removable hard drive, a network share, and so on. Get it from Microsoft's Download Center.

You just made making backups damn easier for me. Now just install it & sync files between my "Files" folder in HD & that of external HD
