How to completely delete a sync store on the cloud drive

I use sync stores on Dropbox.

I am moving to a new sync store and wanted to complete delete the data of the old sync store.- How can i do this?

The Remove Location entry in the sync store’s context menu seems to remove it only from the list but not from Dropbox.

You should have cleaned the sync location before removing it.
Now go into your Dropbox account online, into the Apps/DEVONthink Packet Sync folder and delete the sync store (xxxxx.dtCloud).

Aha! Thanks.
