Purgeable space on external SSD
Hey guys. I've got a couple of external SSD attached to my Mac (running Catalina) that have purgeable data on them. I've been trying to find a way of getting rid of it but all the info I've been able to find only refers to the internal Macintosh HD.
Is there a way of clearing purgeable space on external drives via terminal or any other method?
