Just learned about SyncToy (freeware tool) part of Microsoft PowerToys that provides an easy-to-use graphical user interface for synchronizing files and folders.
PowerToys is written in .NET Framework, synchronized
folders can be on the local PC drive, or on an external device such as a flash drive, or on a network share from another computer (let say via Samba Share). SyncToy can generate scripts which can be later run from command line to do the file synchronization. I’ve done mirror of current SyncToy 2.1 here – http://www.pc-freak.net/files/SyncToy/
