MinIO Uploader

A simple Windows context menu tool to upload files to a MinIO (S3 compatible) server.

Features

• Drag-and-drop or context menu to upload a single file
• Auto-creates a right-click context menu on first run (Current User)
• Hides console window on Windows (GUI subsystem)
• Copies the uploaded object URL to clipboard on success
• Friendly error dialogs for common issues

Requirements

• Windows 10+
• MinIO/S3 endpoint accessible from your machine

Configuration

Create a Settings.toml file with your MinIO credentials. The program will look for the configuration file in the following order (first found is used):

1. %APPDATA%\MinioUploader\Settings.toml (recommended - user-specific, survives updates)
2. Executable directory\Settings.toml (legacy location)

Example Settings.toml:

endpoint = "http://127.0.0.1:9000"  # or https://play.min.io
access_key = "minioadmin"
secret_key = "minioadmin"
bucket = "my-bucket"

Note: On Windows, %APPDATA% typically resolves to C:\Users\<YourUsername>\AppData\Roaming\MinioUploader\Settings.toml.

Usage

• After first run, a context menu item "Upload to MinIO" is added for files.
• Right-click any file → Upload to MinIO.
• On success, the object URL is copied to clipboard.

Uninstalling Context Menu

To remove the context menu registration, run:

minio_uploader.exe --uninstall

This removes the registry entries for the current user only.

Build

cargo build --release

The binary will be at target/release/minio_uploader.exe.

Notes

• Context menu registry path: HKCU\Software\Classes\*\shell\MinIO Uploader\command
• To support folders, also add a similar key under HKCU\Software\Classes\Directory\shell\....
