The first public release of File Mover Express: a high-performance, open-source app for moving media between local storage and Amazon S3, with a desktop GUI, a full CLI, and an MCP server for AI assistants.

High-performance S3 transfers​

  • Auto-tuned parallel transfers using native S3 APIs, with no intermediary servers.
  • Multipart upload and download with configurable chunk sizes and retry on failure.
  • Pause, resume, and cancel active transfers.
  • Transfer priority scheduling and job queue management.

Desktop application​

  • Native desktop app for macOS (Apple Silicon and Intel) and Windows (x64 and arm64).
  • Drag-and-drop file management between the local filesystem and S3.
  • Real-time transfer progress, speed, and ETA display.
  • File browser for both local and S3 with search and filtering.

Hot folders​

  • Monitor local directories for new files and automatically upload them to S3.
  • Configurable inclusion/exclusion filters and deduplication.

Checksums and media integrity​

  • XXH3, XXHash64, XXHash, and MD5 checksum algorithms.
  • MHL (Media Hash List) support for camera-to-cloud verification workflows.
  • Post-transfer integrity verification.

Remote daemon architecture​

  • Run the transfer engine on any machine (workstation, server, or EC2 instance).
  • Control it remotely from the GUI or CLI over an encrypted ConnectRPC connection.
  • Transfer profiles for managing multiple daemon connections.

Command-line interface​

  • Full CLI for scripting, automation, and headless environments.
  • All GUI features accessible from the command line.
  • Scriptable job control (start, pause, resume, cancel).

MCP server (fme-mcp)​

  • A standalone Model Context Protocol server for AI-assisted file transfers.
  • Nine tools: connect, browse local/S3, start upload/download, pause, resume, cancel, and list jobs.
  • Supports stdio and streamable-http transports, so AI coding assistants can manage S3 transfers directly.

Cross-platform​

  • macOS: Apple Silicon (arm64) and Intel (x64).
  • Windows: x64 and arm64.
  • Linux: x64 and arm64 (build from source, or use the CLI/MCP binaries).
