FileIOPermissionAttribute provides declarative syntax support for the FileIOPermission class. The All, Append, PathDiscovery, Read, and Write properties take the full pathname of the file or folder to which access of the appropriate level is granted. Each property represents access as defined by the FileIOPermissionAccess enumeration member of the same name. Unlike FileIOPermission, a FileIOPermissionAttribute can only represent access of each type to a single file or folder; apply multiple attributes to a program element in order to specify access to more than one. Setting Unrestricted to true represents full access to all files and folders.
