Frequently Asked Questions & Customer Support
Find complete technical answers about the NitroBoost engine, Cloud storage setup, and Lifetime License activation via USDT (TRC-20).
NitroFTP is sold for a single one-time payment of 49 USDT (payable on the Tron TRC-20 network) for a Lifetime License. There are no hidden subscriptions or annual fees. All features (NitroBoost engine up to 32 segments, all 9 network/Cloud protocols, and the Nitro Diagnostic tool) are permanently included.
Go to the Buy (49 USDT) page. Copy the Tron receiving address (starting with T...) or scan the QR Code. In your crypto app, select Withdraw USDT, choose the TRX — Tron (TRC20) network, and make sure the net amount received is 49 USDT. Once the transaction is marked completed (~30 seconds), copy its TXID and paste it into Step 3 to immediately receive your NFTP-LIFE-... key.
To guarantee maximum security without forcing the application to phone home to a license server on every startup (100% offline-capable operation), your NFTP-LIFE-... key embeds your NFTP-HWID mathematically signed by our Ed25519 private key. NitroFTP verifies this signature locally in under one millisecond.
When a large file is downloaded in NitroBoost mode, NitroFTP writes data into a temporary .nitropart file and saves the progress map of all 32 segments inside %APPDATA%\NitroFTP\states\. If your PC shuts down or your connection drops, simply restart the transfer: NitroFTP resumes every segment at the exact byte where it left off.
Your configuration is cleanly stored inside %APPDATA%\NitroFTP\ (sites.json, settings.json, trusted_certs.json). Unlike legacy FTP clients that stored passwords in plaintext or Base64, NitroFTP encrypts all your secrets using Windows DPAPI (CryptProtectData) bound to your Windows user session.
