Where is the folder config on the desktop client?

Dear all, I am trying to troubleshoot for someone who has misconfigured his client a lot. Currently the client closes the window after seconds, but otherwise seems to work.

Part of the trouble appears to be that the person is trying to sync huge folders, and the someone is impatient. Huge folders, as in hundreds of GBs.

I would like to verify the configuration of that Nextcloud client. I have looked up the location of the nextcloud.cfg. However, it does not appear to contain the locations of the folder that are confirmed to sync, even if they are beyond the normal boundary.

Where do I find those? I would be very thankful for pointers.
Best,
Wolfgang

I have this in the account section:

0\FoldersWithPlaceholders\1\localPath=C:/Users/username/Nextcloud/
0\FoldersWithPlaceholders\1\journalPath=.sync_xyz.db
0\version=1
0\FoldersWithPlaceholders\1\targetPath=/
0\url=https://nextcloud.example.com

You have the local path and the target path (here the main folder) on the server.
