Plus, it has filtering and customizable versioning settings that help you to set synchronization more precisely. You can also decide how to handle old versions of files and folders: move them to the trash, delete them permanently, or version them in a special folder. The utility is operating as a fully automated solution that seamlessly launches at system startup.
