Ultimate file management and sharing
File Station is a web-based, fast and secure management tool built to allow easy, drag-and-drop operations without requiring any complex setup on Mac or PC. Advanced search and filtering tools allow for easy organization and file sharing. For complete compatibility, DS620slim supports the following protocols: AFP, FTP, iSCSI, NFS, SMB, and WebDAV.

Synchronize files across your devices
Cloud Station Suite provides real-time data synchronization across all your devices and other Synology NAS. "Intelliversioning" keeps the most important file versions to better utilize storage space.

4K Multimedia Server
Access and stream your 4K media content anytime and anywhere. DS620slim supports 4K H.264/H.265 online transcoding via Video Station and DS video, allowing 4K videos to be converted and played on the fly on other computers, smartphones, and media players that originally do not support Ultra HD formats.
