+### How can I automatize the cleaning of old (expired) files?
+
+You can call the admin.php script from the command line (CLI) with the ```clean_expired``` or ```clean_async``` commands: ```sudo -u www-data php admin.php clean_expired```.
+
+Then the command can be placed in a cron file to automatize the process. For example:
+```
+# m h dom mon dow user  command
+12 3    * * *   www-data  php /path/to/jirafeau/admin.php clean_expired
+16 3    * * *   www-data  php /path/to/jirafeau/admin.php clean_async
