Description

If you set this policy, you can list the URL patterns that specify which sites can't ask users to grant them write access to files or directories in the host operating system's file system.

If you don't set this policy, DefaultFileSystemWriteGuardSetting applies for all sites, if it's set. If not, users' personal settings apply.

URL patterns can't conflict with FileSystemWriteAskForUrls. Neither policy takes precedence if a URL matches with both.

For detailed information about valid url patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. * is not an accepted value for this policy.
