Free space on mac differs

My desktop icon shows I have 81,4 GB of my ssd free, meanwhile Commander One shows it's only 31,82 GB (and it's probably closer to the truth). Where the difference come from?


Do you have solid solution to freeing spece on your mac's (how to identify where the bulk of heavy file are). I edit videos on davinci, my cloud service is onedrive. Every idea will be welcomed.

Re: Where the difference come from?


Seems the best, most accurate estimate of storage space on macOS Ventura is:

Apple menu > System Settings,

click General in the sidebar, then click Storage on the right.


Other estimates may or may not include such things as "temporary files" etc., that can be deleted by the sytem if space is short.


NB: Items in the trash are likely to be included in all estimates, and, if deleted,

may also continue to be included until Mac is restarted.


Best first step is always to back up everything, before deleting anything.

Then valuable documents etc., can always be retrieved / restored.

To add to the very good suggestions from @brbo above


Manage Storage


It is generally a good computer practice to alway keep at least 15% to 20% of the Total Drive Capacity’s as Empty Space. Allowing the computer to drop below these guidelines may eventually, cause unintended consequences.


The links below will assist in identifying what is taking up space on the Internal Drive and provide possible ways to remove data that is under the direct control of the User ( Home Folder ) .

Notation - If the user is using a cloning software like Carbon Copy Cloner - suggest tweaking the Safety Net Feature in this software. It may be making additional Snap Shots that are not being Cloned to the Eternal Drive. If this should be the case, these Snap Shot could be using additional space on the drive 


The final word from Apple on Managing the " Other/ System Data “ Category


Other / System Data: Contains files that don’t fall into the categories listed here. This category primarily includes files and data used by the system, such as log files, caches, VM files, and other runtime system resources. Also included are temporary files, fonts, app support files, and plug-ins. You can't manage the contents of this category. The contents are managed by macOS, and the category varies in size depending on the current state of your Mac.
