UFM Pro: A Free Dual-Panel File Manager Optimized for Android TV

A File Manager Truly Built for the Big Screen

In the Android file manager space, the vast majority of apps are designed around phones first. Their support for Android TV / Google TV is often little more than stretching a phone layout onto a large screen — and the experience is terrible. Ultimate File Manager Pro (UFM) was built specifically to address this long-neglected pain point.

According to the developer's post on Reddit, UFM is a dual-panel file manager designed for both Android phones and Android TV. It has surpassed 22,200 downloads on Google Play, holds a 4.7-star rating, and has been featured by CNET. More importantly, the TV version is not a simple port of the phone app — it's a standalone build with full D-pad navigation.

For home theater enthusiasts, NAS users, and heavy TV box users, a file manager that works smoothly with a remote control is worth far more than an ordinary tool.

Background on Android TV vs. Google TV: Android TV is Google's smart TV platform launched in 2014, while Google TV is a next-generation interface layer rebuilt on top of Android TV in 2020, offering smarter content aggregation. Both share the same underlying Android framework, but Google TV significantly improved the UI and content recommendation algorithms. Most smart TVs and TV boxes on the market today (such as the Chromecast with Google TV and NVIDIA SHIELD) run one of the two. Since the primary input method on these devices is a remote D-pad rather than touch, ordinary Android apps tend to perform poorly on TV — which is exactly why apps specifically optimized for TV are rare and valuable.

Core Highlight: The Efficiency of Dual-Panel Design

Side-by-Side Dual Panel

The dual-panel file manager concept traces back to the DOS era of 1987. Norton Commander pioneered the left-right two-column layout, dramatically improving the efficiency of file copy and move operations. Tools like Total Commander and Midnight Commander carried this philosophy forward, making it standard equipment for power users. On mobile, this design lay dormant for years due to screen size constraints. UFM brings it back to large-screen Android devices — in some ways, a revival of classic PC operating philosophy on a modern platform.

At UFM's core is a dual-panel interface: two panels that can be navigated independently, with one side showing local storage and the other showing network shares. This design makes copying, moving, and comparing files far more efficient than toggling back and forth in a single-panel app.

Dual-panel mode is available in landscape orientation on phones, but its advantages are even more pronounced on tablets and TVs — which is why the developer invested in deep TV-specific optimization.

A Full Android TV Experience

The developer emphasizes that the TV version is a separate APK, optimized for the Android TV / Google TV launcher with genuine D-pad navigation. Compared to competitors that simply enlarge a phone UI, UFM's interaction logic on large screens is far better suited to remote control usage. For users managing local media files or external drives on a TV box, this is a clear differentiator.

Privacy and Security: Local AES-256 Encrypted Vault

UFM includes a built-in AES-256 encrypted vault. Users can store sensitive documents, photos, and other files inside an encrypted container, with all data stored entirely on the local device — nothing is uploaded to any server.

AES (Advanced Encryption Standard) is a symmetric encryption standard established by the National Institute of Standards and Technology (NIST) in 2001. A 256-bit key length means a brute-force attack would need to try 2²⁵⁶ combinations — with the most powerful computing resources available today, that would take longer than the age of the universe. AES-256 is used by the U.S. government to protect top-secret data and is the de facto standard for commercial encryption software. Even if a device is lost, an attacker cannot read the contents of an encrypted vault without the password.

Against a backdrop of frequent cloud data breaches, this "data never leaves the device" approach to local encryption provides reliable protection for privacy-conscious users. Compared to encryption schemes that rely on third-party cloud services, local AES-256 encryption offers a simpler, more direct trust model.

Powerful Network and Cloud Storage Capabilities

Broad Protocol Support

UFM covers network storage comprehensively, with out-of-the-box support for:

• WebDAV: An HTTP-based file transfer protocol widely used by private cloud services like Nextcloud and Jianguoyun
• SFTP / FTP: SFTP transmits over an encrypted SSH tunnel for high security, commonly used for remote server management
• SMB (LAN sharing): The native protocol for Windows network sharing, natively supported by major NAS devices like Synology and QNAP
• AWS S3: Amazon's cloud storage standard API, compatible with a wide ecosystem of S3-compatible object storage services (including Backblaze B2 and Cloudflare R2)

The Google Play version additionally integrates Google Drive, OneDrive, and Dropbox. UFM also supports RClone, an open-source tool often called the "Swiss Army knife" of cloud storage, with native support for over 70 cloud storage services and protocols. UFM wraps RClone in a graphical interface, allowing ordinary users to enjoy its broad cloud compatibility without needing to use the command line — theoretically connecting to over 100 cloud providers, with the developer willing to add more on request.

Built-In FTP/SFTP Server

UFM includes a built-in FTP and SFTP server. Users can launch the server directly from the device and then access files from a PC or other device on the local network — no need to install a separate third-party app. For scenarios where you need to quickly transfer files between devices, this removes a lot of friction.

Scheduled Sync Tasks

UFM supports setting up scheduled sync tasks between local folders and remote locations, running automatically in the background on a set schedule. This is extremely useful for users who want to automatically back up to a NAS or home server.

Advanced Features for Power Users

ADB and Shizuku Integration

For users who want deeper file access without fully rooting their device, UFM supports Shizuku and ADB-based operations for elevated access without root.

Shizuku is an open-source Android permission management framework developed by Japanese developer Rikka. Traditionally, accessing Android system-level files requires full root privileges (i.e., modifying system partitions and bypassing security mechanisms), which voids warranties and introduces security risks. Shizuku establishes a service process running with shell-level permissions via ADB; other apps can then call this process through the Binder IPC mechanism to perform elevated operations, enabling access to restricted file paths without root. Users only need to run a single ADB command from a PC to activate it the first time, after which it can restart automatically via developer options — making it the most elegant compromise currently available for users who want deep Android access without the risks of rooting.

Advanced Search

UFM's search function supports filtering by file name, extension, date range, and file size, with fast results that work across local storage and mounted network locations.

Open-Source Version and Business Model

UFM's business model is also worth noting: the Pro version is completely free — no ads, no paywalls — with only an optional tip jar for users who want to support the developer voluntarily.

Furthermore, UFM offers a fully open-source FOSS version under the GPL v3 license, hosted on GitHub. GPL v3 is a strong copyleft open-source license published by the Free Software Foundation (FSF). Its core requirement is that any derivative work based on GPL v3 code must also be released under GPL v3 with full source code when distributed. This is fundamentally different from permissive licenses like MIT or Apache, which allow code to be incorporated into closed-source commercial products. Choosing GPL v3 institutionally prevents the code from being commercially closed off.

This FOSS version strips out all proprietary SDKs and closed-source trackers, including Firebase, Google Play Billing, and proprietary cloud SDKs — further ensuring full transparency across the entire codebase. This is especially significant for users with high security requirements who need to audit where their private data flows.

The open-source version retains network storage capabilities including WebDAV, SFTP, FTP, SMB, and AWS S3, keeping the feature set nearly complete. The only trade-off: if you need integration with major cloud services like Google Drive or OneDrive, you'll need the Play Store version. Pre-compiled APKs are available for direct download from GitHub releases.

This dual-track model of "open-source + commercial version" accommodates both users who prioritize privacy and free software principles, and everyday users who prefer the convenience of integrated cloud services.
