ChronoSync Express is the Mac App Store version of the popular ChronoSync utility. It is an application you can count on for both reliable backups and easy folder synchronization.
To create a new synchronizer document, you just pick two folders and synchronize them. When you need more control, you can use the built-in Options to dictate how individual files are handled, create archives of deleted or replaced files, and customize error handling and notifications. ChronoSync Express brings professional-level features to a consumer-level product.
