All the packages of the anti-virus engines and other technologies will be stored and maintained under an update folder in Central Management.
By default this is C:\Program Files\OPSWAT\Metadefender Central Management\data\update_packages
In order to keep that directory tidy, Central Management provide a cleanup mechanism.
This mechanism is triggered whenever the update process executes and finishes.
Cleanup interval time
All updated Packages that are 24 hours or older than the current cleanup trigger time will be deleted.
