Could it be that you enabled Audit logging for Management Service and entered the path to the root folder.
These settings would give something similar to what you are seeing:
<!-- ****** Audit logging ****** -->
<!-- Enable logging of changes to QVPR. Requires restart of QMS after change. -->
<add key="EnableAuditLogging" value="true"/>
<!-- Folder where audit logs should be stored. Default is ApplicationDataFolder\AuditLog - -->
<add key="AuditLogFolder" value="C:\ProgramData\QlikTech"/>
