NitroFTP is the Windows client for big files and unstable connections: automatic resume after any network drop, up to 10 parallel connections on a single file, and saved passwords encrypted with Windows DPAPI. FTP, FTPS, SFTP, SCP, WebDAV, Amazon S3, Cloudflare R2, Azure Blob & SMB.

Feel right at home with the Quickconnect bar, dual Local/Remote panes, Windows drag-and-drop, Site Manager, and CHMOD—supercharged with the live 32-segment map and real-time Nitro Monitor.
.nitropart FilesWatch every parallel connection work simultaneously on different byte ranges of the same file. If your network drops, transfers resume at the exact byte offset segment by segment.
See the immediate difference in the transfer log: jump from 1.9 MB/s on a single stream to 12.9 MB/s – 48.2 MB/s thanks to dynamic NitroBoost multi-segmentation.
Hosting providers, Seedboxes, and ISPs routinely throttle single TCP streams. NitroFTP breaks through per-stream limits without modifying your Windows registry.
Automatic parallel segmentation using REST + RETR/STOR on FTP/FTPS, parallel offset seek on SFTP, and multipart transfers on S3/Azure.
No more waiting for one slow trailing connection at the end of a transfer: as soon as a fast worker finishes its chunk, it splits the slowest remaining segment in half.
Dynamic Work StealingSO_RCVBUF and SO_SNDBUF buffers are applied to every socket before the initial SYN packet to negotiate maximum TCP Window Scaling over high-latency links.
NitroFTP spawns additional streams as long as real throughput grows by at least +5%, and automatically learns your server's 421 Too many connections ceiling.
Full TLS session resumption on FTPS data channels (required by vsftpd and FileZilla Server), hardware-backed Windows DPAPI password encryption, and anti-MITM TOFU fingerprints.
One-click latency probing on ports 21/990/22/443, ISP DPI throttling detection, optimal MTU discovery, and live 1-stream vs N-stream speed benchmarking.

NFTP-LIFE-...) bound to your Machine ID (NFTP-HWID)FileZilla opens only a single data connection per transferred file. If your remote server, Seedbox, or international routing limits each TCP stream to 2 MB/s, FileZilla will cap out at 2 MB/s even on a 1 Gbps Fiber line. NitroFTP automatically splits each large file into up to 32 simultaneous segments (using REST + RETR/STOR on FTP/FTPS, parallel offset seek on SFTP, or Multipart APIs on S3/Azure) and uses dynamic work stealing so all connections finish at the exact same moment.
Checkout takes less than 2 minutes: 1) Install NitroFTP and copy your Machine ID (formatted as NFTP-HWID-XXXX-XXXX-XXXX-XXXX inside the License window). 2) On our USDT Checkout page, paste your Machine ID and send 49 USDT on the Tron network (TRC-20) to the displayed address (from Binance, Bybit, OKX, Trust Wallet, TronLink, or Ledger). 3) Paste your transaction TXID: our server verifies the transaction on the Tron blockchain and immediately displays your Ed25519-signed NFTP-LIFE-... key.
No, zero global system or netsh changes are made. All TCP optimizations (pre-SYN SO_RCVBUF / SO_SNDBUF buffers and native SIO_KEEPALIVE_VALS keep-alive) are applied strictly to the network sockets created by NitroFTP.
Yes! In addition to classic protocols (FTP, Explicit/Implicit FTPS, SFTP, SCP), NitroFTP natively integrates WebDAV/WebDAVS, SMB/CIFS, Azure Blob Storage, and all S3-compatible object storage providers (Amazon S3, Cloudflare R2, MinIO, Wasabi, OVHcloud Object Storage) with high-speed parallel transfers.
