SyncFolder was written because every backup utility eventually wants to turn into a file management system with automated backups and fileset etc, but sometimes you have a folder and want it backed up.

SF is geared to giving you the most flexibility with your copy. You can choose to keep deleted and changed files and they will be kept in a folder that can simply copied over the original folder to restore it if things go wrong.

You can also lock folders against overwrites, runs tasks in parallel or serially and save task sets for reuse.

You also can scan the backup first to verify the changes before commiting a backup.
