For those getting started, this helper screen breaks out the four most basic functions. If you have used a file synchronizer for any length of time, you will probably use the "Advanced" mode.

I happen to like the home-grown artwork. Don't let it fool you into thinking SuperFlexible is anything less than a robust, fully developed synch utility. I have used many different synch products over the years, on both Mac and PC. This is right up there with the best. There is enormous power, and yes, flexibility, under the hood.
