I just posted praise for FullSync here. While FullSync may not be the best tool for file syncing, it works great for me across multiple use cases and edge cases. At the same time, I have come across other software to do the same task. I’ve tried some of these software for a few weeks to compare the usability and found these to be great. Specifically, Always Sync, SyncToy, and SyncBack are nice-to-know options. They can sync data over a local network too.
Dropbox and Adobe Creative Cloud file sync work by uploading your data to a cloud. So these work across geographies. Such software also use Internet bandwidth and are not the most suitable options to transfer files available locally on a LAN.
