My Galaxy S9+ showing 42 GBs of System files.. How can I clean up this?

System files+user data is just about everything stored on the phone - your apps, the apps' data, Android, Linux ...

The only way to "clean it up" is to delete files and/or uninstall apps.

It's not abnormal. My Pixel 2 is using just under 68GB of storage at the moment. (Of course, a lot of it is apps I've installed to help people with, and haven't uninstalled yet, but it's still probably using over 50GB.)
