Your phone/laptop acts only as the controller , not the storage medium . The file moves directly between two remote locations (cloud storage, VPS, NAS, etc.). ┌─────────────┐ Control Signal ┌─────────────────┐ │ Controller │ ─────────────────────→ │ C2C Manager │ │ (Your PC/ │ │ (Core Engine) │ │ Phone) │ ←───────────────────── │ │ └─────────────┘ Status Updates └────────┬────────┘ │ Direct Transfer (no controller) │ ┌───────────────────────┼───────────────────────┐ ↓ ↓ ↓ ┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ Source A │ ──────→ │ Source B │ │ Source C │ │ (HTTP/FTP/ │ Data │ (Cloud │ │ (NAS/ │ │ S3/BTFS) │ Flow │ Storage) │ │ Server) │ └─────────────┘ └─────────────┘ └─────────────┘ Key Features | Feature | Description | |---------|-------------| | No Local Storage | Files never touch your controller device | | Remote-to-Remote | Transfer directly between two URLs/remotes | | Multi-Protocol | HTTP, HTTPS, FTP, SFTP, S3, WebDAV, IPFS, BitTorrent | | Resume Support | Interrupted transfers resume from last byte | | Bandwidth Shaping | Limit speed per transfer | | Scheduling | Run transfers during off-peak hours | | Web UI / CLI | Control from anywhere | | Notifications | Telegram/Discord/Webhook on completion | Example Use Cases 1.
