Hello,
I have a folder shared with multiple devices (each device belongs to a different user). I need to know who created/modified/deleted a file or a folder, I’m wondering if there is any way to do that with Syncthing?
Thanks!

There is a -verbose -audit command line switches which cover what you are after.

Thank you @AudriusButkevicius, that’s helpful! I need to fetch this info from a node app (in real time) running on the same server where the shared folder is. For instance, when a new file/folder is created, the node app (which is watching the directory for changes) saves this new file/folder into a db along with other info. I would like to also store which user last updated/modified a file or folder. Is there any way I can do that without having to parse log files?

I see we have [this endpoint](https://docs.syncthing.net/rest/db-file-get.html) on the REST API, which has the `"modifiedBy": "523ITIE"` field, and I probably can make a GET request for every file change detected from the node app. Would you say that’s the way to go? Although I don’t see a similar endpoint for folders, is there any that I’ve maybe missed?

Ok… I don’t know how I’ve missed that but I’ve just found out there’s an [event api](https://docs.syncthing.net/dev/events.html) which we can subscribe to using long polling, and that covers my use case with the [RemoteChangeDetected event](https://docs.syncthing.net/events/remotechangedetected.html)! Thanks for the help and apologies for the noise!
