The Toolbox section of the April 2007 TechNet Magazine highlights a tool called Allway Sync.
No matter what kind of IT job you have, chances are you spend a lot of time moving files and directories from one place to another—whether from your desktop to a USB key or from server to server over the network. Often, it’s important to keep those directories synchronized to ensure you aren’t creating unnecessary duplicates and that you’re working with the latest version of the files. Sometimes you may need to synchronize files and directories across many machines, as when deploying static XML or HTML files across a set of Web servers. Allway Sync from Usov Lab is a helpful tool for handling these kinds of tasks.
