Best strategy for syncing "recent" files only

For example I have directory called Work_Orders on my main workstation and via syncthing I sync it to my phone. This works as expected but I have been doing it for years now and the directory is getting large as some child directories contain images and other large files. My initial thought was to use rsync to mirror the Work_Orders directory but only files created within the last N days and than sync that directory to my phone via syncthing. Is this a good way to accomplish this or is there a better solution that I am overlooking?


Sounds like that would work.
