Thanks for the info - checked the website - Though it has some good reviews it seems it is not for novices like me as from the info one needs to be technically inclined to understand the technical language and make droplets etc?
FileBuddy is available as a 10-day trial. You might want to give it a try (no need of droplets) or you might find TidyUp
a better choice.
Personally, I use a shell script but I understand that terminal use is beyond your wishes…
