PortFlow is a Windows-based file transfer and backup project focused on reliable, low-footprint automation.

This repository contains two related efforts:

• PortFlowBackup — a finished, shippable Windows utility (v1.0.0)
• PortFlow (Core) — ongoing development toward a larger, configurable file-flow engine

PortFlowBackup is a lightweight Windows utility that automatically runs a robocopy-based backup when a specific USB or external drive is inserted.

Download:
➡️ Go to the Releases page and download PortFlowBackup.zip

Note: The compiled .exe files are not included in this repository. All executable binaries are published as GitHub Releases only.

1. Extract PortFlowBackup.zip
2. Run install.cmd as Administrator
3. When prompted, edit portflow.backup.json
4. Copy PORTFLOW_TARGET.txt to the root of your backup USB drive

After setup, backups run automatically whenever the target USB drive is inserted.
