EV remove archive with dvs files

Hi

I have EV 9.0.2, and two partitions, VSTORE1 and VARCH

VARCH contains archives for disabled users or users who don't work in our company anymore. 

So now I need to remove those archives from VARCH to create more free space on this partition. 

I removed about 100GB but nothing has changed with free space. I noticed that archives have gone from EV Console in Exchange Mailbox, but free space on partition hasn't changed. 

What should I do to increase free space ? I thought that EV will remove .dvs files for those archives which I removed. 

Regards
