Windows Desktop Client excluding folder from syncing

Hello, when using the old sync logic, I was able to check a local subfolder to be synced with the target. This option is not possible anymore with the new virtual file sync. The client is always showing, that it is syncing the content of this subfolder.

I use it with additional applications like Joplin, to store my notes on the nextcloud via webdav. But I do not need it within my sync folder. Currently I get a notification in the sync client for every Joplin note which is created. (When I use the virual files feature.)

Is there a work around for this problem?

Problem solved. I could fix it with the ignored file list.
