# allowedDirectoriesAndFiles The set of directories and files that remain visible in the Finder during an assessment. ``` var allowedDirectoriesAndFiles: Set? { get set } ``` ## Discussion Defaults to `nil`, which leaves Finder unrestricted. Setting a non-`nil` set hides everything except the given locations; pass an empty set to hide all of them. This restricts what the Finder displays. It doesn’t sandbox participants, which can still reach other paths programmatically. Entries that aren’t file URLs are ignored. --- Copyright © 2026 Apple Inc.
