there is what I want it to:
HOST only received will take all data from clients.
Client PC 1,2,3 only sent with different data.
All of them not full sync like how the syncthing work, I mean to be it just to save store.
How to setup it correct way. If I share main folder from HOST to every Clients, after few syncs all pc will show out of sync, If I overwrite, data in HOST will lose
