Simply Powerful

Does one thing and does it well!
It can sync folders or whole drives. You can choose what to exclude. It can sync both ways or you can choose to have the source completing the target. You can choose to always confirm the sync operation (useful for deletes). It can keep syncing in the background and it’ll auto-mount your network drive if you want. You can have as many sync operations as you want, each with different settings. The UI is very simple — it’s just a list of sync operations. When there’s an error, it shows a detailed error log so you know what’s going on.
