AndSMB

Why is your file server so difficult to access from a mobile device?

If you rely on SMB (Server Message Block) file sharing to transfer documents, media, or backups between your computer and mobile devices, you know the pain. Native Android file managers often lack stable SMB support, require complex manual IP configuration, or crash when handling large transfers. AndSMB, developed by LYSESOFT, solves this specific problem: it provides a dedicated, optimized SMB client that turns your Android device into a full-featured network file browser. This is not a generic file manager with SMB tacked on—it is a purpose-built tool for accessing Windows, NAS, and Linux shared folders over a local network.

Core Functionality: How AndSMB Works

AndSMB operates as a standalone SMB 1.0, 2.0, and 2.1 client. Upon launch, it scans your local Wi-Fi network for discoverable shares using automatic network discovery (SSDP and NetBIOS). You can also manually add servers by IP address or hostname. Once connected, the app presents a dual-pane interface: a list of accessible shared folders on the left and the contents of the selected share on the right. File operations include copy, move, rename, delete, and compress. The app handles large file transfers (5 GB+) with resume support and maintains persistent connections even when the device goes to sleep, provided you configure the battery optimization exception.

Key Advantages Over Default Solutions

• Bidirectional streaming support: Play video and audio files directly from the shared folder without downloading them first. AndSMB uses the device’s native codecs, so MKV, MP4, AVI, and FLAC files play smoothly.
• Encrypted connection handling: Supports NTLM and Kerberos authentication protocols. It also works with SMB signing enabled on modern Windows 10/11 and Synology DSM 7+ servers.
• Background transfer queue: Add multiple files to a download queue, close the app, and transfers continue in the background (requires Android 8+ notification channel permission).
• LAN-only operation: No internet connection required after installation. All traffic stays within your local network, reducing data usage and latency.
• Network drive mapping: Save frequently accessed shares as bookmarks with custom credentials. The app remembers authentication tokens across sessions, eliminating repeated logins.

Recommended Usage Scenarios

• Accessing a Windows 10 shared documents folder from an Android tablet
• Copying photos from a phone to a Synology NAS without using the vendor’s proprietary app
• Managing media files on a Raspberry Pi running Samba
• Transferring backup archives between a laptop and an Android phone over 5 GHz Wi-Fi

Technical Disclaimer

This application requires a stable Wi-Fi connection to local network servers; cellular data will not function for SMB discovery or file transfers. AndSMB does not include a built-in file viewer for all formats—external apps handle playback and document rendering. In-app purchases may appear in later versions for additional protocol support or concurrent connection limits. Background transfer performance depends on Android battery optimization settings; disable power saving for AndSMB if you encounter transfer interruptions.
