Publish services
With publish services you export and sync photos to a folder or online service in Lightroom Classic, and keep that collection up to date. If you edit a photo later, Lightroom marks it as modified so you can republish it. That way a folder or gallery always matches your catalog.
You set up a publish service (to a hard drive or a service via plug-in, for example) and drag photos into it. Lightroom remembers what's already published and what's still to go, so you don't have to track it by hand. This is nice for a fixed export folder you want kept in sync with your selection. Tip: use a publish service for your 'ready to deliver' folder, then it always holds your current, final versions.
