Freeing up space · Local snapshots and held space
What does the message at the bottom of Local Snapshots tell me after I delete something?
Short answer: It's the outcome banner showing the result of your last action — what was deleted or reclaimed and anything that couldn't be. A failure on one snapshot never stops the others.
That's the outcome banner: the result of your last action in the window — how many snapshots were deleted or how much was reclaimed, and anything that couldn't be done. You can dismiss it when you've read it.
If one snapshot fails to delete, the others still go ahead and the banner says so. After any deletion the list refreshes; use Refresh at the top to re-check at any time. See Is it safe to delete local snapshots?
