How to reduce disk usage?

From control panel >Storage I'm told that my MacHD has 127Gb of applications.

Expanding that, it tells me that Pages is using 69.97Gb

Show that in Finder and it's only reporting 686.1Mb.

Where can I find what is using the missing 69.3Gb?

All files, documents etc are only ever saved on external drives.

Mac mini, macOS 15.6

The bar and categories in the Storage eye candy, have not been accurate for some time now.


To get a good break down of where things really are, I use OmniDiskSweeper.

It begs the question


Why is it required to find the space ?


Is the computer running out of Free Space ?


Has the computer exhibited unusual behaviours ?


Has the computer alerted the user that " computer is running low on Space " ?


To really see the Used versus Free space


Disk Utilities knows, best
