SyncToy is a free PowerToy for Microsoft Windows XP. The beta program was launched in August 2005 and was also mentioned on this blog (http://blogs.technet.com/chitpro/archive/2005/08/06/408757.aspx).

Now version 1.0 download is available for free. The SyncToy provides is an easy to use, highly customizable program that helps you to do the heavy lifting involved with the copying, moving, and synchronization of different directories. Most common operations can be performed with just a few clicks of the mouse, and additional customization is available without added complexity. SyncToy can manage multiple sets of folders at the same time; it can combine files from two folders in one case, and mimic renames and deletes in another. Unlike other applications, SyncToy actually keeps track of renames to files and will make sure those changes get carried over to the synchronized folder.
