AWS Releases Open-Source File Mover Express
Amazon Web Services has launched File Mover Express, a free file transfer application for macOS, Windows, and Linux designed for large media and data transfers.
Updated on Nov. 1, 2026 in Software

Amazon Web Services released File Mover Express, an open-source file transfer application licensed under Apache 2.0 and available for macOS, Windows, and Linux. The tool supports parallel transfers, automatic performance tuning, retries, pause and resume, and file integrity verification.
Why it matters
Media teams frequently move terabytes of assets between on-premises storage and the cloud under tight deadlines. Traditional transfer clients may stop when a desktop session ends, while commercial alternatives can add licensing costs, proprietary protocols, or third-party infrastructure.
The application splits large files into chunks for parallel multipart uploads and calculates checksums in the background, caching them locally. Its daemon-based engine decouples transfers from the desktop session, and the extraction does not include throughput measurements.
The players
Amazon Web Services (AWS)
Amazon Web Services is the cloud computing division of Amazon that provides on-demand computing, storage, and software services to businesses and developers worldwide.
The details
The application offers a drag-and-drop graphical interface alongside a scriptable command line interface, and supports single sign-on through OpenID Connect. Its daemon can run on a workstation, a data center server, or an Amazon EC2 instance, controlled over an encrypted, password-protected connection, and its source code is available on GitHub.

The Tech Race
File Mover Express extends AWS's EC2 infrastructure by offering a transfer tool that can run on an EC2 instance as well as on local workstations. It positions AWS to compete with commercial file transfer products by releasing a free, open-source alternative with a permissive Apache 2.0 license.
Developers and media teams can use the free tool to move large files between workstations and the cloud without relying on a desktop session staying open. Its checksum verification and resume features help confirm that transferred files arrive intact.
The takeaway
Teams handling large file volumes can evaluate open-source transfer tools that run on either local hardware or cloud instances, reducing dependence on proprietary clients. Verifying checksums and enabling resume features can help protect large transfers from data loss.
