Allway Sync is a file synchronization software that allows users to sync files and folders in multiple locations such as local drives, network drives, and cloud storage. It supports bidirectional and one-way syncing, as well as scheduled and real-time syncing. The software also has a feature called "propagation" that ensures that changes made in one location are reflected in all other synced locations. Additionally, Allway Sync has a user-friendly interface and supports a wide range of file types.
