Not for the feint of heart, but amazingly powerful. Reliable. UI isn’t too easy.
There is nothing in the program to tell you which mode you should use: A<=>B or A<->B or A<+>B or A+>B or A<+B or A=>B or A<=B or A-B. Yet, this is the single most important setting.
Really, the selection should be documented. And, the drop-down descriptions should be more obvious. Perhaps this part of the program needs re-thinking to be more clear.
Also, it’s not really obvious that the first tab is one item from the list of items on the second tab.
I was able to figure this all out because as it turns out I used this program under Windows 6 years ago. (What a surprise for me to find it.)
Now, the program is superb. It works incredibly well. It’s really amazing. It is fast and reliable. It can sync up millions of files. It is a spectacular piece of work, which is why I still gave it 5-stars. The ability to do real-time syncing makes this just extra special and perfect for a data center where you keep replicated copies of files.
So I would say this is a high-end proghram for experienced computer users. It’s an outstanding file synchronization app. But the user interface is mediocre.
