How do I free disk space in Libvirt?


I am using OpenSUSE Leap 42.2 on a Dell Inspiron 1545.
I previously had a 12GB storage volume in Libvirt. Then, I deleted it. Shouldn't that have freed 12GB of space?
But the room in the storage volume is only 8.9GB. The filesystem is Btrfs. Is there a disk cleanup tool like Windows has? How do I free space?
Maybe the disk is fragmented.
You would think that deleting a 12GB volume would free 12GB of space. But it doesn't?

No, you wouldn't think that if you did a small amount of research.

Until you stop whatever process is keeping that file open, the space won't reflect a change. Common in every operating system. Your disk is not fragmented, and never needs a 'cleanup' like Windows.
