Advanced search and filtering tools allow for easy organization and sharing of files with just a link. Supports SMB, FTP, AFP, NFS, WebDAV, compatible with any environment.

Easy file access with QuickConnect

Access files on your Synology NAS over the Internet without the hassle of setting up port forwarding rules, DDNS, or other complicated network settings. QuickConnect allows you to connect via a simple customizable address (e.g. https://customID.quickconnect.to), so that you can instantly access media and work files on any Windows/Mac/Linux computer, laptop, or mobile device without additional charge.
