Palo Alto Networks provides several precanned scripts, such as 'delete_file', 'quarantine_file', and 'process_kill_name', that are used for endpoint management and security. The 'list_directories' script, however, is not one of the standard precanned scripts offered by Palo Alto Networks. This script is more commonly associated with basic file system operations rather than specialized cybersecurity tasks that Palo Alto Networks focuses on. Therefore, 'list_directories' is not a precanned script provided by Palo Alto Networks.
