Trying to understand APFS
I formatted my 500 GB SSD with APFS in Big Sur, and I have, as expected, MacHD and MacHD-Data (I shortened the names).
Before the format, I created a clone onto a TB Firewire drive. After the format and installing apps from scratch, I drag-copied contents of my Documents folder into MacHD's Documents.
So at first I thought whoops, I should have put documents into MacHD-Data, but then again, why were the Big 7 folders created -- Desktop, Documents, Downloads, etc. -- on MacHD? My background of a partition comes from the days of DOS, and I'm trying to wrap my head around APFS. What is the point of MacHD-Data? When opened, it's (visually) empty.
