EV 10 File System Archiving populatebillingaccount

Hi Experts,

First questions, I have EV 10 FSA server and in Archive general properties for users, the "Bill usage to" is blank. Is PopulateBillingAccount registry value applicable to EV FSA?

Second Question, if yes (from above), from EV FSA reporting, will this show the number of users accessing the archives?

Thanks,

Will
