Description
Allow access to local files by letting Microsoft Edge display file selection dialogs. If you enable or don't configure this policy, users can open file selection dialogs as normal. If you disable this policy, whenever the user performs an action that triggers a file selection dialog (like importing favorites, uploading files, or saving links), a message is displayed instead, and the system interprets the action as a Cancel selection in the file selection dialog.
