OneBox Shop is unavailable (out of disk space)

Good day. Today when trying to enter CRM https://gorgany.crm-onebox.com/dashboard/ gives an error about the location. We cannot clean the disk, because apart from the browser we have no access. << Uncaught ConnectionManager_Exception: Cannot connect to database: Connection refused in /var/www/newalphademocrm/web1/web/packages/ConnectionManager/ConnectionManager_MySQLi... You probably ran out of disk space >> There was already such a problem 4 days ago and it was quickly solved on the forum. https://1b.app/ua/support/server-installation/12004-hmarna-versiya-nedostupna-quotymovirno-zakinchilos-mistse-na-disku/ A similar situation was also in July, but then we managed to clean the files (mostly PDF). Is it possible to disable the download of large files, or files of a certain format, or all attachments from mail to Onebox? And if it were possible to reserve a place for such cases, it would be ideal. That is, the minimum functionality to enter the admin panel and delete files.
