None the devices on my Syncthing have “untrusted” turned on, but I’ve got a bunch of syncthing-enc folders. I tried shutting down syncthing, deleting them, and then starting it again but to no avail. It’s a bit of an issue because there’s big files stored in there and I don’t want them all doubling up.
Also of note this is being displayed in the console (once for each syncthing-enc folder) every now and then
syncing: handling dir (setting permissions): chmod REDACTED/N.syncthing-enc: operation not permitted
The “untrusted” tickbox is only an additional precaution to prevent yourself from sharing folders other than Receive Encrypted by mistake. You can still share a mix of Receive Encrypted and other type folders without ticking the “untrusted” box.
