I’ve used the free FileZilla client for basic FTP and SFTP stuff for years and it’s fine, but I keep juggling separate apps and browser tabs for our S3 bucket and Google Drive on top of it. Pro supposedly bundles all of that into one interface, but before I hand over money I’d rather hear from people who actually paid for it instead of just reading the marketing page. Anyone here upgraded and willing to share the honest good and bad?
I’ve used FileZilla Pro for a little over a year. The short version is that it handles transfers well, especially large files and unreliable connections, but the interface and a few security concerns keep it from feeling like a polished paid app.
The transfer side has been dependable for me. I’ve moved individual files larger than 100GB without problems, and App Store reviews mention similar results. One reviewer said they transferred a 600GB file that other apps couldn’t handle. It also works reasonably well over spotty Wi-Fi and VPN connections.
The main reason to pay for Pro is the cloud support. S3, Google Drive, OneDrive, Dropbox, and Azure appear alongside your normal server connections in the same window. If you regularly move files between FTP servers and cloud accounts, that’s genuinely convenient.
There are some downsides. The interface looks dated, and several Capterra reviewers compare it to software from the early 2000s. That seems fair. I’ve also run into occasional slowdowns that didn’t appear to be caused by my network. Other users report the same thing, though most describe it as an annoyance rather than a dealbreaker.
Security is worth checking before you settle on it. G2 reviewers have warned that passwords may be stored in plain text with certain configurations, so look into that if security is a major concern. The value of the Pro upgrade is also debatable. You get more connection methods, but at least one reviewer felt it still fell short of dedicated paid FTP clients in the same price range.
If you want alternatives, CloudMounter takes a different approach. It mounts FTP, SFTP, and cloud storage accounts as local drives, so you can manage files through your usual file browser instead of opening a separate transfer client. Cyberduck is free and supports many of the same protocols and cloud services. Mountain Duck is another option if you want mounted drives on both Mac and Windows.
FileZilla Pro basically does what it promises. Whether it’s worth paying for depends on how often you’ll use the extra cloud connections. If a trial is available for your setup, I’d test it with your normal servers, cloud accounts, and a few large transfers before buying.

Expect Pro to save clicks, not transform the FileZilla experience. If cloud accounts are only an occasional need, the free version plus a browser is cheaper; pay only if moving between servers and cloud storage is part of your weekly routine.
If you mainly upload finished folders, FileZilla Pro makes sense. If you expect cloud storage to behave like another drive for opening, editing, and saving files throughout the day, it’s probably the wrong tool.
That distinction matters more than transfer speed. Pro keeps the same basic FileZilla workflow, so you’re paying for additional connection types rather than a smoother or more modern application. @xrustybadgerx is right about saved clicks, but I’d go further: frequent transfers can justify it, while frequent file access may become tedious.
For drive-style access, something like CloudMounter may fit better because the storage appears in your normal file browser. For queued uploads, large batches, and retrying interrupted transfers, FileZilla Pro is the more natural choice. Whichever route you take, use SFTP or another encrypted protocol where available, and avoid storing credentials without protecting them with a master password.
Don’t buy FileZilla Pro expecting a backup or synchronization tool. It transfers files, but it won’t protect you from overwriting a newer copy, resolve conflicts, or automatically keep two folders matched. That distinction gets missed when people see cloud support on the feature list.
For deliberate jobs such as “send this completed folder to S3” or “download these files from OneDrive,” Pro is a reasonable purchase. Reliability is generally less predictable when you start doing thousands of tiny files, repeated renames, or transfers between two remote services. Cloud APIs can throttle requests, and an interrupted job may need more checking than the queue status suggests. I would test your messiest real folder, not a single large file.
Security depends heavily on your setup. Pro doesn’t make ordinary FTP safe, so use SFTP, FTPS, or the provider’s encrypted cloud connection. Pay attention to saved passwords, master-password settings, certificate warnings, and SSH host-key prompts. Clicking through those warnings removes much of the security you thought you were getting.
I slightly disagree that mounted-drive software is automatically better for frequent access. CloudMounter is more convenient in Finder or Explorer, but editing a remote file directly can be risky if the connection drops while saving. For important work, downloading locally, editing, then uploading through a visible queue is slower but easier to verify.
My practical cutoff would be simple: buy Pro if cloud transfers are a repeated task and you want them in the same queue as FTP or SFTP jobs. Keep the free version if cloud use is occasional. The upgrade adds destinations, not a better interface, automatic backup, or a safer workflow by itself.
Cloud support can be listed as compatible and still be unusable with your actual work account. Company-managed Microsoft, Google, or AWS accounts may restrict third-party sign-ins, require admin approval, or enforce login rules that make the connection less convenient than expected. Testing with a personal account won’t tell you much if the real job uses an organization-controlled account.
The familiar FileZilla layout has another downside here: it makes cloud storage look like an ordinary FTP server. That is easy to understand, but cloud permissions and object storage behavior do not always map cleanly to folders and files. A harmless-looking rename or move may involve a lot more work than expected, and FileZilla’s interface may not expose every provider-specific setting you care about.
I agree with @silentmaker1528 about testing a difficult folder, but I’d test the entire login and permissions setup too. Connect the exact account you plan to use, close and reopen the program, verify that authentication still works, and try uploading, downloading, deleting, and overwriting a disposable file. If this is for business use, give FileZilla access only to the storage locations it actually needs rather than handing it broad account permissions for convenience.
For normal FTP or SFTP work, paying for Pro does not seem to buy much beyond the extra destinations. The free version already covers the basic transfer workflow, so reliability and ease of use will feel largely familiar. Pro makes more sense when switching between those servers and cloud accounts is wasting enough time to become annoying.
My cutoff would be whether it works cleanly with your real cloud account and its security policies. If it does, the unified queue can justify the purchase. If authentication needs repeated babysitting, or you need detailed control over cloud permissions and metadata, the promised convenience disappears pretty quickly.
The hidden cost is that Pro may not replace your cloud provider’s desktop app, so you can end up maintaining two workflows anyway.
First try the free FileZilla for FTP/SFTP, then use Google Drive, OneDrive, or Dropbox’s sync app for cloud files. If that setup creates too much downloading, copying, and re-uploading every week, Pro is worth buying for the unified transfer queue. If it only saves a few clicks occasionally, keep the free version.
The plain text password worry from @tom1999 is a bit outdated. FileZilla added a master password option a while back, so credentials get encrypted if you actually turn it on. Just don’t skip that step, because the default still leaves them readable.
Repeated transfers are where Pro starts to feel like the wrong upgrade.
If you keep sending the same folders to the same S3 bucket or Drive location, a free tool such as rclone or the provider’s command-line client may save more time. You can script the job, apply include/exclude rules, run a dry test, and keep a log. There is some setup involved, but after that you are not dragging files through the same interface every week. This builds on @silentmaker1528’s point: FileZilla Pro is a transfer client, not an automation or synchronization system.
I’d list your three most common jobs before paying. If they are random, visual tasks where you need to inspect folders and manually choose files, Pro is a sensible convenience purchase. If they are predictable jobs like “upload this export every Friday,” spend an hour testing rclone first. FileZilla Pro solves app switching, but it does not solve repetitive clicking.
