But the freeware version is seriously short of capability such as incremental/differential/auto folder name etc. etc. etc.
To get the sort of capability I wanted you still have to pay - and memeo is a heck of a sight easier to use and quicker in operation. It also sits nicely in the background and just works. Everyone to their own of course, but it's worth trying a few free trials first and then settle on the one that best suits.
