Xnode Usage and Data

Xnode Usage and Data

What exactly is stored in the folder <installdir\\ManageEngine\ADAudit Plus\apps\dataengine-xnode\data\main. This folder is now larger than my MSSQL DB that hosts Auditplus 7051. My DB is 80 GB but this folder is 100 GB. I'm wondering what AuditPlus uses it for. I know its related to the windows services 'ManageEngine ADAudit Plus - DataEngine XNode'. Be great to get a deep dive on it. Can anyone advise?
