Over the last few years I've got more and more concerned about how MacOS file store behaves. One very specific concern is if I delete files to create more working space, for example to make new installations easier, or just simply because an application may create quite large output files. This is also particularly important for doing systems upgrades or application updates, which often won't work unless there is sufficient working space.
What I find worrying is if I delete a large file, the space taken up by that file often does not seem to be returned back to the system. Closing the system down, then rebooting will usually recover some of the space.
Some while back I found one tool which seemed to be backing up deleted files - Disk Drill (which was producing large files - with a name something like .cleverfiles) but although I suspected it was a rogue application (which I had installed for a very specific purpose..) I've never actually positively identified it as malware. However, as far as I know, that is not currently installed, and is not active on my MacBook Pro.
Now I wonder if it's just something which Apple have initiated - which wouldn't surprise me much.
Currently this is a pain, as I've noticed that some Apple applications have new versions and are awaiting installation, yet now it seems that Apple have created new versions of applications which won't even work in Catalina - but only in an updated version of Catalina - 10.15.6. So in order to keep applications up to date I also have to update the OS yet again.
This is just such a complete nuisance.
Backing store memory seems to disappear, and makes updating software or the OS really rather difficult.
