I've started to use Maintenance module and noticed that files in filestore directory are not removed after deleting attachments. Is any simple method to make a cleanup of unused files or I need to write a script which will be doing it?
I know, that using hash of files instead of real names is useful when the same files are attached many times and therefore is not so easy to delete file directly after removing attachment but I hope a cron script would be very desired.
