* “Scooter Software”:http://scootersoftware.com Beyond Compare. Wow, this is a treally terrific shareware utility for comparing files and then copying them. It is very fast over a network. Just what I need at home where unfortunately syncing is a big problem.
* “7-Zip”:http//7-zip.org. I actually use this all the time since it includes the functionality of both WinRAR and Winzip and it is actually freeware.
