Hi,
Thanks for your posting. Per my search and test, you could get the IP address or Computer name when there are users opening the shared folder either from computer management or poweshell command.
1.Computer management 2.net session command
If you would like to check the historical record in event logs, you shall enable Audit File Share and look for event ID 5140:This event generates every time network share object was accessed. It contains source IP address from which access was performed.
