Sharon,
Do subgroups have individual features like files, calendar, etc.?
Yes.
My test group has subgroups if you want to test or create some before making a permanent change to your real group. Note that the web/email address format for a group which has subgroups is different, and that change cannot be undone by deleting the subgroups.
And do subgroup¡¯s files, photos, etc. count toward the parent group¡¯s
storage limit or are they treated like individual groups?
The primary group and its subgroups are added together for the limits. Mark briefly changed it to separate limits, but put it back a couple days later.
