Recursive Sync Search and Destroy?

Is there a way to figure out if I have a recursive directory synch within my clients?
Specifically: I have multiple Windows computers with the Nextcloud agent installed.

Is there a way to check that those directories are not getting synced one inside another?



Any ideas if this is possible?

Any thoughts on this possibility?
