Thanks. This is great. And the reason "why" I wanted to do this is that sometimes I want to overwrite a file and sometimes I want to keep versions (depending what option I choose in a Prompt). I had already been using the timestamp idea but this seems neater.
It might be worth mentioning that your example Macro only needs these three Actions to make unique versions of a Write System Clipboard to File Action. I do find this "Create Unique" option quite confusing, but you have clarified it for me with your example.
