3. Download & Installation

  1. Download RFD_v6.2.zip from this website
  2. Extract the ZIP file to any folder
  3. Run RFD_v6.2.exe — no installation needed
  4. The config.json file stores your settings
⚠️ Your antivirus may flag the exe due to the anti-tamper security layer. This is a false positive. See our FAQ for details.

4. Quick Start

  1. Paste links from any file-hosting site (FuckingFast, DataNodes) or repack page (FitGirl, DODI)
  2. Set thread count — 8-16 for most connections, 32 for gigabit+
  3. Choose output folder — preferably on an NVMe SSD
  4. Click Download — sit back and watch the speed
💡 For FitGirl repacks: Copy the entire HTML block with all part links. RFD extracts and queues every file automatically.

5. Features in Detail

Multi-Threaded Download Engine

Each file is split into segments downloaded via separate HTTP connections. With 32 threads, you effectively bypass per-connection speed limits set by file-hosting servers.

Async NVMe Flushing

At speeds above 500 MB/s, traditional disk writing becomes a bottleneck. RFD buffers data in memory and flushes to disk asynchronously, preventing UI freezing.

HWID Licensing

PRO licenses are bound to your hardware (CPU ID + Baseboard + Disk Drive). This prevents license sharing and piracy.

Anti-Tamper Security

Built-in detection of memory scanners (CheatEngine, x64dbg, Process Hacker). XOR-obfuscated strings and SHA-256 self-verification prevent code modification.

6. Troubleshooting

Antivirus False Positive

Add RFD to your antivirus exceptions list. The detection is caused by anti-tamper code, not malware.

Downloads Failing

Check your internet connection, try reducing thread count to 8, and ensure the file-hosting site is accessible.

PRO Activation Issues

Ensure you're using the correct HWID key. Contact support if your hardware has changed.
