    SyncManager

    SyncManager

    Sync manager that helps you sync your files across different locations

    SyncManager is a custom-made lightweight synchronization manager that helps you synchronize files and folders across different locations.

It also offers three distinct synchronization types: two-way, one-way, and one-way update, allowing you to synchronize data between folders in different ways. 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.
