Trying to get each archive size...

Hi all,

I am running EV 9.0.2 and I have a request to get a real time size of each archive in the vault, I know there is a report that could find this but I am wanting to give the end users a tool that can be run real time to get the size of their Archive. 

Anyone know of any commands that I can run to pull this information from the vault?

Many thanks
