Question: HD space available miscalculated
High Sierra seems to miscalculate the free HD space available? Look how the individual folders does not add up any where near to the 384 GB in total. After taking this screenshot I looked in my user system folder and found a 40 GB folder from a crypto app which I didn't need. After deleting this 40 GB folder the total GB used went from 384 to 290 GB and the free space went up 3 GB.
500 GB TOTAL HD (SSD) (Subfolders doesn't add up)
384 GB USED
20 GB FREE
It appears High Sierra has a 'math problem' ???
