Nice, also compression at file system level can save a lot of space and with current CPU speeds is completely transparent. It is feature from HFS+ that is still works in APFS, but is not officially supported anymore, what is wrong with you Apple ?

This tool to enable compression is free and open source

Also note about APFS vs HFS+, if you use HDD e.g. as backup media for Time Machine, HFS+ is must have over APFS as it is optimised only for SSD (random access).

Not so smart Time Machine setup utility forcefully re-creates APFS on a HDD media, so you have to manually create HFS+ volume (e.g. with Disk Utily) and then use terminal command to add this volume as TM destination

`sudo tmutil setdestination /Volumes/TM07T`
