An FTP client is the program a person uses to connect to an FTP, FTPS, or SFTP server and move files around. Think of the server as a filing room and the client as the messenger you send in to drop off and pick up folders. The protocol underneath is old — FTP, the File Transfer Protocol, dates to the early 1970s — but choosing an FTP client still matters today, because partners expect these protocols, regulators still accept them, and a large share of business file exchange runs over them.

This guide walks through how to choose an FTP client that fits your work: what you're connecting to, which protocols you need to speak (FTP, FTPS, SFTP, WebDAV, S3), and whether you want the experience to feel like a file manager or like a regular folder on your desktop. If the terms FTP and SFTP are new to you, what FTP is and how it works and what SFTP is are good places to start before you pick a tool.

How FTP Clients Got Here

The first FTP clients were text-only. You typed commands one at a time — connect, log in, list the directory, get a file, put a file — and the tool did exactly what you said and nothing more. That worked for the engineers who built the early internet, but it kept everyone else out.

Then came the graphical clients in the 1990s, tools like WS_FTP and CuteFTP that put two folder panes side by side: your computer on the left, the server on the right, drag a file across to move it. That picture is still how most FTP clients work today.

The other big shift was security. Plain FTP sends your password and your files as readable text, so anyone watching the network can grab them. To fix that, two encrypted versions appeared: FTPS (FTP wrapped in the same encryption your browser uses for HTTPS) and SFTP (file transfer carried over SSH, the same secure channel admins use to log into servers). Encryption is now the default expectation, which is part of why web browsers dropped their built-in FTP support — they didn't want to ship an insecure connection. That browser change is exactly why a dedicated FTP client is worth choosing well.

The FTP Clients Enterprise Teams Actually Use

A handful of clients cover almost every real-world need. Here's what each one is good at.

FileZilla. Open-source and free, runs on Windows, macOS, and Linux. It speaks FTP, FTPS, and SFTP, has the classic two-pane drag-and-drop layout, and handles large transfer queues well. It's the default first pick for a lot of teams because it's free and works everywhere.

WinSCP. Windows-only, and a favorite of Windows admins. It does FTP and SFTP plus SCP and WebDAV, and its real strength is automation: you can script transfers and run them from the command line, which is handy for recurring jobs.

Cyberduck. Runs on macOS and Windows, and reaches beyond plain servers — alongside FTP, SFTP, and WebDAV it connects directly to cloud storage like Amazon S3 and Google Drive. Easy to use, with bookmarks for the servers you visit often.

Transmit (Mac only). A polished, paid macOS client known for fast transfers and a clean interface. It speaks FTP, SFTP, and WebDAV and connects to cloud storage too. If you live on a Mac and want the nicest experience, this is the one people reach for.

Files.com Desktop App. The native client for Files.com accounts, on Windows and macOS. Instead of a separate two-pane window, it plugs into Windows File Explorer and Mac Finder so your remote files show up as ordinary folders. You get the full set of Files.com features — share links, automated workflows, audit logging — without leaving the file manager you already use.

How to Choose the Right FTP Client

Five questions sort out which client fits. Work through them in order.

What protocols do you need to speak? This is the first filter. If a partner only accepts SFTP, you need a client that does SFTP. If you also touch FTPS and a couple of S3 buckets, pick a client that covers all of them so you're not juggling three tools. Match the client to the servers you actually connect to.

Does it run on your operating system? Sounds obvious, but it eliminates options fast. WinSCP and Transmit are single-platform (Windows and Mac, respectively); FileZilla and Cyberduck cross platforms. If your team is mixed, a cross-platform client saves you supporting two sets of instructions.

Will you need server-to-server transfers? Moving a file from one remote server straight to another — without it stopping on your laptop in between — is a job most desktop clients do badly, because the file has to travel down to you and back up again. That work belongs at the platform layer, not the client layer. Files.com handles it natively with Remote Server Sync and the Files.com Agent, so the file moves directly between the two endpoints.

How comfortable are you at a keyboard? If you just want to drag files now and then, pick the client with the friendliest window. If you're automating nightly jobs, pick one that can be scripted from the command line — WinSCP is the common choice there.

Do you need automation and a record of what happened? Occasional manual transfers don't need much. But recurring jobs — sending a report every night, syncing a partner folder on a schedule — are far more reliable when the platform runs them for you instead of someone remembering to click. And in any regulated industry, you'll eventually be asked to prove who moved which file and when. A plain client can't answer that; a platform with an audit log can.

Where a Managed Platform Comes In

A client is only half the picture. The client is the messenger; something still has to run the filing room it connects to. For a single person grabbing files off one server, any good client is enough. But once you have partners, recurring transfers, and an auditor who wants to see the records, the question stops being "which client" and becomes "what's the client connecting to."

That's the gap Files.com fills. Files.com is the cloud-native File Orchestration Platform: one platform that replaces the stack of legacy tools IT teams run to move files — SFTP and FTP servers, MFT suites, file-sharing apps, and the scripts holding them together. It speaks every protocol, connects 50+ cloud and on-prem systems, automates every transfer, and keeps a complete audit trail. Your people and partners keep using whatever FTP client they like — FileZilla, WinSCP, Cyberduck, the Files.com Desktop App — and connect over FTP, FTPS, SFTP, WebDAV, or an S3-compatible API to the same managed endpoint.

What you stop doing is running the server. There's no FTP box to patch, no capacity to plan, and no separate audit tooling to wire up: every login and every transfer is recorded for SOC 2 Type II and HIPAA, and a file arriving over any protocol can kick off an automated workflow on its own. If you just want to mount an FTP or SFTP server as a drive on your Mac or Windows desktop, ExpanDrive does that. But once the job grows into managing transfers for a team, Files.com is the platform the clients connect to.
