I like best that it gives me an easy way to compare large documents, so it makes sure there are no errors in copying or pasting files from one computer into another. It's not perfect yet - sometimes you have problems getting some folders synced up correctly with other computers that use your network share as well even if those shared files were last copied/pasted only minutes earlier by AraxiMerge itself. There isn't much more than what we need for our daily uses of comparing different copies with each other. We're using this specifically because our organization has many people working at various locations who work remotely frequently but still want access to their own copy of certain important docs when they get back together again later that day; then these same users can easily see changes others might make without having to wait until everyone gets back together next time around where someone else will be able to do any additional editing.
