DS File: Direct Mobile Management for Your Synology NAS

This is the official mobile client for users who operate a Synology NAS running DSM 6.2 or later. DS file provides direct, encrypted access to your network-attached storage from your Android device, transforming your smartphone into a remote file management terminal. The application supports the HTTPS protocol for secure connections, ensuring that every file transfer and browsing session is protected against interception. Whether you need to retrieve a spreadsheet for a meeting, stream a 4K video to your tablet, or back up photos from a business trip, DS file delivers the tools required for precise file operations without relying on third-party cloud servers.

Core File Operations and Remote Access

The application is built around three primary functions: browse, transfer, and manage. You can navigate the entire directory structure of your Synology NAS, including shared folders, subdirectories, and system volumes. The file manager supports standard operations such as copy, move, rename, delete, and compress, all executed directly on the NAS hardware. For bulk operations, you can select multiple items simultaneously and apply actions across folders. The remote access feature allows you to connect to your NAS from any location with an internet connection, bypassing the need for a local Wi-Fi network. This is particularly useful for professionals who need to retrieve critical documents while traveling or for users who manage multimedia libraries from a distance.

Integrated Media Playback and Document Preview

DS file includes a built-in media player that supports a wide range of video and audio codecs. You can stream content directly from the NAS without downloading the file to your device first, saving local storage space. The player handles formats such as MP4, MKV, AVI, and MOV for video, alongside MP3, FLAC, and AAC for audio. For documents, the application provides a quick preview feature for common file types including PDF, Microsoft Office documents (DOCX, XLSX, PPTX), and image formats like JPEG and PNG. This eliminates the need to install separate viewer apps for basic file inspection. The preview loads only the necessary portion of the file, reducing bandwidth consumption during remote access.

Security and Connection Configuration

DS file prioritizes connection security through multiple authentication layers. You can configure the app to require a passcode or biometric verification (fingerprint or facial recognition) before accessing the NAS. The connection itself uses HTTPS encryption by default, with options to enforce certificate validation. For advanced users, the application supports QuickConnect ID, which provides a simplified connection method without manual IP address configuration. Additionally, you can set up automatic connection fallback: if the primary connection method fails, the app attempts alternative routes such as relay servers. This ensures uninterrupted access even in network environments with restricted ports or firewalls.

Task Management and File Sharing

The application includes a task manager that tracks active file transfers, including uploads and downloads. You can queue multiple operations, pause and resume transfers, and view progress indicators for each task. For sharing files with external contacts, DS file generates secure download links that expire after a configurable period. These links can be sent via email or messaging apps, and recipients do not need a Synology account to download the files. The sharing feature also supports password protection and link expiration dates, giving you control over who accesses your data and for how long.

• Secure file sharing with expiration links

Why This Matters for Daily Operations

The application eliminates the friction of transferring files between devices using cables or cloud intermediaries. Instead of uploading to a third-party service, you access your own storage infrastructure directly. This reduces latency, maintains data sovereignty, and keeps your files within your private network. For professionals, this means instant access to project files without waiting for sync. For home users, it means streaming a movie from your NAS to your phone without buffering issues caused by cloud servers. The interface is optimized for touch controls, with gestures for navigation and long-press actions for file properties.
