Macintosh HD - Data

I have been cleaning my MacBook Pro, running Catalina, from tons of photos and useless data and thought I would have regained a ton of disk space, until I opened disk utility and saw that most of the disk (93.95 GB of 121GB) was now taken up by Macintosh HD - Data. What gives?

Catalina now consists of two volumes: the Mac HD which is now only read (no write access at all and contains your OS and its system files) and the Mac HD - Data which contains everthing else - your applications, files, pics, videos, etc, etc - that is read/write so you have access to it.


That is what it is - nothing really changed as far as space is concerned; just within different volumes now.
