Resilio Sync allows you to automatically sync files between computers via secure, distributed technology (P2P bittorrent protocol). Fast, intelligent file transfers. Sync skips the cloud and finds the shortest path between devices when transferring data. No Cloud. No uploading to third party servers. Just fast, simple file syncing. Use your local network You don't need the Internet to use Sync. Sync can utilize local networks even if the Internet is down or unavailable. You can even set up a router in a place with zero internet access to share data over a private network. Intelligent synchronization. Incremental updates After you edit an existing file, Sync knows how to update only the parts that have changed rather than the entire file. This makes updates much faster, especially for large files. Continuous synchronization and updating Keep all of your shared folders up to date all the time across all devices. Updates and changes are synchronized immediately and automatically. Pause specific folders You can pause syncing for specific folders, or for everything at once. If you're in a situation with extremely limited connectivity you can turn off everything but the most important folders to ensure that information is synchronized as efficiently as possible.

On-demand access to files. Save space with placeholder files When 'Selective Sync' is on, Sync will create placeholder files in your filesystem that can be searched locally. Download only the files you need, when you need them, without having to replicate entire folders on every device. Placeholder files are representations of your files that can be double-clicked and downloaded locally. Access massive files when you need them Don't want to sync the entire contents of a folder to your device? Turn on 'Selective Sync' to save space. You can choose to only sync files on-demand, when you need them.
