FTP, SFTP, FTPS, security posture, integration playbooks, and field reports from the team behind the ExaVault on-premise appliance — now part of Files.com.
FTP uses port 21 for control and port 20 (active) or an ephemeral high port (passive) for data. SFTP uses port 22. FTPS uses port 990 for implicit TLS. Here's the breakdown, the firewall implications, and how modern cloud platforms make the port question obsolete.
Modern browsers no longer support FTP, so the old "type ftp://… into the URL bar" trick is gone. Here's how to access an FTP server today — from your desktop, from any modern client, and from a cloud-hosted platform like Files.com that handles FTP, SFTP, and FTPS in a browser-based UI.
Active FTP and passive FTP are two ways the protocol handles its separate data connection — and the choice between them determines whether your transfers work through a firewall. Passive mode is the modern default. Here's why, how each one works, and what to do when the data channel won't open.
SFTP and FTPS both encrypt file transfers but they're very different protocols underneath. SFTP runs over SSH on a single port; FTPS is FTP wrapped in TLS with all of FTP's dual-channel quirks. Here's how each works, the five differences that actually matter, and when each is the right choice.
WinSCP scripting and automation: the WinSCP.com CLI, scripted session syntax, .NET assembly for deeper integration, logging, SSH key auth, and the failure-mode design that makes scheduled jobs actually reliable.
Why is FTP slow? Diagnose the actual cause — local network, intermediate hops, FTP-protocol overhead, or server-side bottleneck. ping, MTR, iperf3, and the order-of-investigation that gets you to the answer in under an hour.
FTP is the original cleartext protocol. FTPS is FTP wrapped in TLS. SFTP is not actually FTP — it's a subsystem of SSH. Here's the real difference, which one to pick for a new deployment in 2026, and why most teams are retiring all three in favor of a managed platform.
A branded FTP site puts your logo, colors, and domain on the file-sharing surfaces your customers and partners actually see — share links, upload portals, email notifications, the login page. Here's what's worth branding, what to avoid, and how white-label managed-file-transfer platforms handle it.
Financial services file transfer workflows — client document intake, audit-firm exchange, bank reconciliation feeds, year- end close, partner ACH/wire submissions. Each has its own protocol shape and compliance driver. Here's the practical guide.
Where FTP actually shows up in e-commerce — product catalog feeds, image and asset delivery, vendor EDI, marketplace integrations, dropship order routing — and where modern alternatives (REST APIs, webhooks) have replaced it.
Connect WinSCP to an SFTP server using an SSH key instead of a password — for passwordless login, automated scripts, and stronger security. Step-by-step with screenshots: generate a key pair, import the private key into WinSCP, convert it to PuTTY format, test the connection, save the site.
Monitor FTP and SFTP file transfers with notifications, polling, webhooks, or activity logs. Each method has different latency, reliability, and operational overhead. Here's the comparison and which to pick for your workflow.
Sharing sensitive documents with employees, partners, and customers — without leaking them. The practical comparison: cloud sharing, share links with passwords and expiry, encrypted email + PGP, SFTP, and managed file transfer. Which fits which threat model.
FTP and SFTP both support resuming interrupted transfers, but the mechanics differ. Here's how the REST command works in FTP, how reget/reput work in SFTP, what your client actually does when it resumes, and how to debug the common failure modes.
FileZilla is the most-used FTP client, but it isn't always the right one. Seven solid alternatives — Cyberduck, Transmit, Forklift, WinSCP, WS_FTP, Core FTP, and the drive-mounting clients — with honest recommendations for which OS, which workflow, and which budget.
HAProxy best practices for production load balancing and failover. Health checks, fallback backends, TCP balancing for non-HTTP services including FTP, database health checks with mysql-check, graceful reloads, and when to reach for something other than HAProxy.
FileZilla is more than quickconnect. Directory comparison, synchronized browsing, regex file search, site manager customization, and the keyboard shortcuts that make daily use faster. Here's the guide to the features most users never discover.
Setting up an FTP server in 2026: the DIY path (provision Linux, install vsftpd/ProFTPD, configure auth, harden, open firewall) vs the hosted path. Step-by-step for both, with the operational costs most teams miss when picking.
MTR (My Traceroute) is the network diagnostic tool that combines ping and traceroute into a single continuous probe. Here's how to read the output, what each column actually means, the common patterns you'll see, and how to tell ISP rate-limiting from a real network problem.
Set up your first SFTP file transfer in under 10 minutes. Pick a client (FileZilla, WinSCP, Cyberduck, Transmit), configure the connection, transfer a test file, verify the host key. The practical walkthrough for getting from zero to working SFTP.
SFTP stands for SSH File Transfer Protocol — a file-transfer subsystem of SSH that runs over a single encrypted port. Here's how SFTP works under the hood, why it's not the same protocol as FTP, and how modern hosted platforms have replaced self-managed SFTP servers for most teams.
A practical hands-on tutorial for FTP and SFTP — how to connect with FileZilla, the OS-bundled command-line clients, and a real-world automation library. Side-by-side examples of every operation so you can pick the protocol and tooling that fits your workflow.
SSH is Secure Shell — the network protocol behind SFTP, behind remote-server administration, behind nearly every secure connection between admins and servers. Here's what SSH actually is, what makes it different from shh-quietness, and why it's the foundation of modern secure file transfer.
An FTP server is a piece of software that listens for FTP client connections and exchanges files over the FTP protocol. Here's how it works under the hood — the protocol exchange, the popular open- source implementations, the operational concerns, and how modern managed platforms have replaced self-hosted FTP for most teams.
SSH keys give you stronger authentication than passwords plus passwordless login for automated workflows. Generate a key pair with ssh-keygen, install the public key on the server, and authenticate without typing a password again. Step-by-step with the common gotchas.
Compare self-hosted SFTP servers (OpenSSH, ProFTPD, Cerberus) with hosted SFTP services. Which fits which size team, the real cost comparison, and the operational concerns most teams underestimate when picking between them.
FTP stands for File Transfer Protocol — the original 1971 protocol for moving files between computers over a network. Here's how FTP works under the hood, what it's still used for in 2026, and how modern managed-file-transfer platforms have replaced self-hosted FTP for most teams.
The honest comparison of secure file transfer methods — SFTP, FTPS, HTTPS uploads, AS2, encrypted email, consumer cloud sharing, and managed file transfer platforms. What each one is actually good at, where each one fails, and how to pick for your situation.
Retail and e-commerce file transfer involves more than uploading product photos. EDI partner exchange, product-catalog feeds, inventory and order data, image and asset delivery, and PCI-aware customer data — each has its own protocol shape and security posture.
The essential FTP commands you'll actually use, plus the full protocol-level command list grouped by category. Includes the CLI reference for the standard `ftp` client, what the wire- protocol verbs (RETR / STOR / PASV) mean, and which commands carry over to SFTP.
FTP and SFTP solve the same job differently. Here's a practical decision guide for picking between them — what each protocol does, how each one works, and which one fits your specific workflow, partner mix, and compliance posture.
FTP is 50+ years old and still in active use across architecture and construction, transcription and print, web development, finance, retail and hospitality, and media distribution. Here's why each industry still relies on FTP — and where the modern alternatives have started taking over.
FTP software comes in two flavors — clients (FileZilla, WinSCP, Cyberduck) that you run on your desktop, and servers (vsftpd, ProFTPD, OpenSSH) that listen for connections. Here's what each does, the popular options, and how to pick the right one for your shape of work.
The honest options for sending large files in 2026 — email attachments (the limits), free services (WeTransfer, Smash), cloud sharing (Dropbox, Google Drive), SFTP, and managed file transfer platforms. Which one fits your file size, security posture, and audit needs.
