Hi and apologies if this has been asked multiple times. I couldn`t find a similar post.
What is the best practice for syncing a folder with a device, whose parent folder is already synced with other devices? a) is this a good idea at all? b) how do you deal with versioning? will this result in any conflict?
Here`s the filestructure:
parent folder
- subfolder A
- subfolder B
- subfolder C
the whole parent folder incl. all subfolders gets already synced between 2 devices. Now there is a 3rd device which only should receive and sync subfolder B.
Hope that makes any sense.
Thanks for any advise!

If I understand correctly, you have a parent folder being synced with a peer (“One”), and a sub folder being synced with another peer (“Two”). I also understand that Peers One and Two are not, themselves, peers.
This should just work the way you explain it. Rock on.

Thanks for the response! Now I am not sure if I understand you correctly. Apologies, let me try it again:
There are 4 devices:
- Device A (Unraid NAS)
- Device B (MacOS)
- Device C (Ubuntu)
- Device D (Win11)
(C+D dualboot on the same machine)
A B C share the parent folder
D should only sync one of the subfolders inside the parent folder
What is the best way to achieve this, without messing things up?
🙂

Share the subfolder separately from A or B.
I’m _assuming_ this is a separate copy of the data compared to what is on C and the dual booting part is irrelevant apart from the fact that both C and D can’t be online at the same time.
If, on the other hand, you’re trying to share some of the data between C and D on a common partition but have them as different Syncthing installations with different configs, do not. You will not accomplish this without messing things up.

Thank you! Yes, I can confirm, that C + D run on different partitions, even different phyiscal disks, and yes, they are never online at the same time.
So you are saying, I should setup the subfolder as a new sync folder on D and share for example with A - the NAS that is always on?
That does not lead to versioning conflicts, even if that folder is already shared as part of the parent folder between A,B,C?
