For some reason that makes no sense my boot drive seems to have dropped about 70 gigs in free space recently. I know drive space goes up ad down a little on High Sierra, but this seems excessive.
Looking just now in the finder I saw three folders that I hadn't seen before and wondered if there is a connection. The first is called Backup, then there is one called Support that has a folder inside called SuperDuper. Finally there is a folder that is simply named OS.
All of these folders appear to be empty, but it does seem odd that they are visible and I am suddenly losing all this drive space. Anybody know what is happening here?
