There have been multiple discussions about this in the past and some starting attempts (including a recent set of pull requests) but nothing has made it into the mainstream syncthing yet. This is not an easy thing to implement, but I do wish someone with more intimate knowledge of the code would take a serious crack at it.

For me this is still a really important feature. I think the ignore list capability means that a good bit of the underlying code may be ready for this kind of feature. But the fundamental problem of a lack of inte… --- _[View the full topic](https://forum.syncthing.net/t/replacing-existing-nextcloud-syncing/21629)._
