Use case: I have users who are folder owners on the file server; today the folder owners can see users, and user groups regarding permissions, but not who are in the groups. The Folder owners has to audit all access to the folders every 6 months.  

Can I make a workflow, for audit of permissions every 6 months to a folder on fileserver inclusive showing User group’s members?

If not:

Can I make Report for each user running every 6 months, that pull the permissions from a folder on a fileserver (inclusive User group’s members)? and mail it the folder owners.
