There must be a snapshot referencing those files and that is the reason why they keep using the space.<br>
Check hammer(8) manpage on how to operate snapshots.<br>

Hello,<br>
<br>
Im a newbie to BSD as a whole.<br>
Currently my company has a backup solution implemented in dragonfly BSD<br>
with hammer.<br>
My question is simple, is there a specific way to remove a file/folder in<br>
hammer.<br>
<br>
The situation is like:<br>
<br>
I moved 65G data to one of my directoies /Backup under a specifc directory.<br>
When I removed it the the files and folders have been removed but the<br>
occupied space remains.<br>
I have done hammer cleanup and prune but to no avail.<br>
<br>
<br>
Can you please guide me on where Im going wrong.<br>
