System Storage question?

[leprekon666]

I was just wondering as I have 20gb of system storage and I believe the Mojave macOS was 11gb. What exactly is in the system storage. I also have this 1.7gb in other container, is that this vm thing? Sorry but new using a MacBook and read online but kind of gets confusing as many things show up when google and YouTube searching. I have only had this MacBook Air for like 2 weeks.

Thanks but I have done that but not sure why my system storage is 20gb when the OS is only 11gb. I deleted all the default apps as I don’t use them. Am I missing something or is it swap storeage or is that what volume container is. I’m used to Windows so I just want to understand when I am a little confused when I search about volume container, swap storage and vm.

/Library is included in "system", along with other non user files.

Many similar threads on this subject. Faster and easier if you just look for them. Here is example:

I summary: files get deleted later, not when you delete them. Just in case you would still like them back later. Space will be released when needed (purged) or eventually at some point. Designed to be used and not studied. Ignore it until you actually have problem. It seems to usually work just fine.
