VaultStore disk usage not reducing after deleting old files from File Server ?

Hi All,

I have deleted a couple of Terabytes directories from my File server which has got FSA agent installed, however when I look at the Vault Store partition drive usage in the EV 9 server, the disk space is not reduced ?

What should I do to make sure that the disk space is also released or reduced for all of the items that I have deleted in the file server.

Thanks.
