sys.dm_filestream_non_transacted_handles (Transact-SQL)

Displays the currently open non-transactional file handles associated with FileTable data.

This view contains one row per open file handle. Because the data in this view corresponds to the live internal state of the server, the data is constantly changing as handles are opened and closed. This view does not contain historical information.
