DeviceControl Folder size increasing

DeviceControl Folder size increasing

We have a server who has endpoint central agent installed. The folders "C:\Program Files (x86)\ManageEngine\UEMS_Agent\DeviceControl\device\fa\backup" and "C:\Program Files (x86)\ManageEngine\UEMS_Agent\DeviceControl\device\fa\main" are rapidly increasing in size.  What are these files and is it safe to remove older files?
