Transferring files between Android and Linux has long been a challenge for many users, particularly due to the inherent differences between operating systems and the limitations imposed by certain transfer protocols. In a context where fast, secure, and wireless data exchange has become a necessity, a new free application has recently changed the game. It enables seamless transfer between a Linux device and an Android terminal, leveraging modern technologies to simplify these exchanges. This solution integrates perfectly into the open source ecosystem and meets the needs of system administrators, developers, and regular users seeking an effective alternative to traditional tools such as Filezilla or Syncthing.
Installation and Technical Configuration of the Android-Linux Transfer Application
The ease of installation of this application, called Packet, makes it an accessible tool even for those unfamiliar with handling complex packages on Linux. Distributed as Flatpak, it benefits from support for popular distributions such as Ubuntu, Fedora, Debian, Pop!_OS, and Manjaro, which already have the universal Flatpak manager preinstalled or easily integrated.
Installation is done with a simple terminal command:
- flatpak install flathub io.github.nozwock.Packet
This command triggers the download of the package from Flathub, the centralized and secure source for Flatpak applications. The user is prompted to choose between a system or user installation. Once the installation is complete, the software is immediately available without the need for complex configuration, thanks to a simple and intuitive interface designed for quick setup.
On the Android side, no need to install any additional applications. Indeed, Packet uses the native function Nearby Share, integrated into most devices since Android Marshmallow, which offers a file sharing protocol using Wi-Fi Direct and Bluetooth. This only requires that both devices are on the same local Wi-Fi network, which guarantees a fast and secure connection without consuming mobile data.
The prerequisites are minimal:
- A Linux device with Flatpak installed and sudo access for installation.
- An Android device equipped with Nearby Share (Android 6.0+).
- A common Wi-Fi network accessible to both devices.
- Port 9300 open on Linux firewall for default receive option.
This simplicity of installation and commissioning confirms the desire to provide users of a free environment with a practical and homogeneous solution for file transfer that can be easily integrated into daily work chains.
Detailed operation and daily use of file transfer between Android and Linux
Once installed, the use of Packet is based on a simple and effective principle which avoids many of the pitfalls encountered with heavier applications like AirDroid or ShareDrop. The program automatically detects Android devices present on the same network and offers intuitive sharing without additional complexity.
Here is a step-by-step guide to transfer a file from Linux to Android:
- Connecting to the common Wi-Fi network: The devices must be connected to the same network, which avoids risks associated with an unstable internet connection or complex NAT configurations.
- Selecting the file to send: In the main Packet window, the user clicks “Add File” and selects one or more files via the file explorer.
- Launching Nearby Share on Android: In the Files app on Android, open the Quick Share option, which activates the receive function.
- Sending the file: The Android device automatically appears in the Packet interface on Linux. Simply click on the device name to trigger the send. The Android user accepts the receipt via the usual notification.
- Managing the send: After transmission, the interface allows you to remove the file from the send list to avoid automatically resending the same items during future sessions.
Receiving files works the same way, but a static port configuration on Linux is required. This is configured in the Preferences menu by enabling the corresponding option and then opening port 9300 using the following command:
- sudo ufw allow 9300
Receipt is then operational, with automatic saving to the ~/Downloadsdirectory, a standard location that’s easy to find and compatible with all file managers. This method eliminates the need to use FTP like Filezilla or complex synchronization solutions like Syncthing.
Packet therefore presents itself as a lightweight and fast tool, with the fluidity of an application designed for local exchanges, avoiding the overload of unnecessary features. Its natural integration into the Linux ecosystem is a plus, facilitating its rise to popularity among professional users and discerning amateurs.
Comparison with other popular Linux-Android file sharing tools
In a world where fast file transfer is paramount, several solutions compete for the favor of Linux-Android users. Among the alternatives, names such as Filezilla, Syncthing, Pushbullet, ShareDrop, Snapdrop, Send Anywhere, AirDroid, Treasure , and Feem come up frequently.
Here’s a comparative analysis to better understand where Packet fits in:
- Filezilla: A classic for FTP/SFTP transfer, it excels at network transfers but requires a server configuration, which is often cumbersome for mobile and local use. Additionally, it doesn’t natively support direct Wi-Fi sharing protocols. Syncthing:
- Excellent for real-time multi-device synchronization, it goes far beyond simple one-time transfers, but its peer-to-peer architecture requires a more technical setup and is sometimes too cumbersome for occasional quick transfers. Pushbullet:
- More notification and sharing-oriented, where files, links, and messages converge. It requires an internet connection to function, which can be limiting on a closed local network. ShareDrop and Snapdrop:
- Very practical web-based alternatives for cross-platform sharing, but depend on an external internet connection and sometimes a recent browser, which can slow down sending or pose privacy concerns. Send Anywhere:
- Offers a simple, cross-platform interface with one-time code exchange, ideal for temporary security but requires an internet connection. AirDroid:
- The former king of Android wireless transfers, this comprehensive app is powerful but cumbersome, with often invasive management of notifications, ads, and additional services. Treasure and Feem:
- Applications specialized in local sharing, without an internet connection, place Packet in the same lightweight category. However, Packet stands out for its extreme simplicity and its native Linux Flatpak integration. Packet therefore combines the best of both worlds by offering a local and painless transfer, fast, secure, and suitable for everyday use. This lower technical barrier and the fact that it’s completely free make this tool essential for those looking to avoid the complexity or constraints of cloud or server solutions.

Managing file transfers between Android and Linux inevitably raises important security and compliance issues, particularly in professional contexts or in multi-user mode. The Packet solution, which leverages Nearby Share, adheres to local sharing best practices:
Transfers are confined to the local network, significantly reducing the risks of data leaks over the Internet or through untrusted intermediaries.
- The activation of a specific network port (9300 by default) is controlled, with the ability to modify this setting, allowing the configuration to adapt to advanced firewall rules, as detailed in some guides on configuring network bonding on Ubuntu.
- Choosing a destination directory configured in the preferences limits the exposure of sensitive data, in accordance with the best practices observed when calculating SHA fingerprints on Linux.
