Deleting files doesn't free up space on Mac, try these solutions

If you are also one of those who are troubled by Mac free space not changing after deleting files, you can wait for a moment to check if the available space is updated. If not, follow the workarounds below to get out of the dilemma.

Here are all the possible methods to fix 'deleting files but not freeing space on Mac':

1. Close the document or other files before deleting

If you are editing a document and meanwhile delete it, a new document will be generated when you finish editing. So, before permanently cleaning up the files from your Mac, stop using them and close them. Or else, you'll find that deleting files doesn't free up space on your Mac.

2. Ensure you've emptied the files from Trash

Maybe, you forgot to empty the files that you've put into Trash. So these files are still on your Mac startup disk. You can open the Trash bin and check if your deleted documents, installers, or other files are there. If they are, select them and then right-click to choose Delete Immediately. Or you can click the Empty button in the Trash folder to permanently remove all the files in Trash.

Now, you can open Disk Utility in Launchpad or click the Apple menu > About This Mac > Storage to check if the available space is increased or not.

3. Restart Mac

Commonly, the capacity of free space will be updated immediately after the time you delete files from your Mac. But sometimes, the system occurs temporary errors, leading to the task of updating free space lagging or getting stuck. And a Mac restart can fix these errors and refresh the macOS. Thus, you can reboot your Mac to see if the usable disk space is increased.

4. Disable Time Machine and disconnect your backup disk

Some users illustrate that the Time Machine may be the troublemaker that results in deleting files but not freeing space on Mac. Once you enable Time Machine, it saves local snapshots on your Mac about every hour and keeps them for 24 hours. And your Mac calculates the space occupied by snapshots as available storage (the purgeable space).

Perhaps, the time when you remove files from your Mac, Time Machine also creates the local snapshot with a similar capacity. Hence, you still can't store other files on the limited storage on your Mac. That is why you regard that deleting files doesn't make the space increase. And if you back up your Mac to an external hard drive at the same time, Time Machine will also save an additional snapshot once the backup finishes.

So, you can temporarily disable Time Machine in System Preferences and disconnect the Time Machine backup disk until you free up a large amount of available disk space. And turn off Time Machine will also enable Mac to delete the no longer required local snapshots.

5. Deleting files in Safe Mode
