FileZilla doesn't have a single "Dark Mode" toggle in its settings, which can be frustrating since it's a classic Win32 application that doesn't always automatically follow modern Windows personalization settings.
Here is an interesting guide to getting that sleek dark look, depending on how much you want to "hack" your system. 1. The "Official" Way (Global System Settings)
FileZilla relies on the system colors provided by your operating system. To change FileZilla's background, you have to change your entire Windows theme to a high-contrast dark version. Go to: Settings > Accessibility > Contrast Themes. Select: A dark theme like "Aquatic" or "Dusk."
Result: FileZilla will instantly turn dark, but keep in mind this affects all your programs, including File Explorer and Word. 2. The "Semi-Official" Way (MacOS & Linux)
If you're on a Mac or a Linux machine, you have it much easier.
MacOS: FileZilla Pro and newer client versions automatically follow your macOS system-wide dark mode.
Linux: Change your GTK theme to something like Arc Dark. FileZilla is built on wxWidgets, which pulls directly from your GTK settings on Linux. 3. The "Visual Only" Hack (Custom Icons)
If you can't stand the high-contrast Windows theme, you can at least update FileZilla's icons to look better against a dark background.
Download: Modern icon sets like Papirus FileZilla Themes from GitHub. Install:
Extract the icons to FileZilla’s resources folder (usually in Program Files\FileZilla FTP Client\resources).
Open FileZilla and go to Edit > Settings > Interface > Themes. Select your new, darker icon set. 4. The "I'm Done With This" Alternative
Many long-time users have switched to WinSCP because it offers a native, built-in dark mode toggle that doesn't require messing with Windows settings. It can even automatically import all your FileZilla bookmarks and passwords during installation. PapirusDevelopmentTeam/papirus-filezilla-themes - GitHub
Since FileZilla has not released a native "Dark Mode" update for Windows (it still uses the default system gray/white colors), the "update" you are looking for involves manually applying a theme patch or using Windows system settings to force a darker appearance. filezilla dark theme upd
Here is the guide to getting a dark theme in FileZilla.
Until FileZilla adds native dark mode, the most consistent dark experience is:
.fztheme.The glow of the dual monitors was the only light in the room, carving a harsh, rectangular sun into the gloom of the apartment. It was 2:00 AM.
Elias squinted at the screen, his eyes burning with that specific dry, gritty sensation that only comes from a twelve-hour coding marathon. He was knee-deep in a critical server migration, transferring gigabytes of sensitive data for a client whose deadline was "yesterday."
On the left monitor, his code editor was a soothing landscape of dark grays and soft blues—a comfortable darkness. But on the right monitor, FileZilla blazed like a nuclear reactor.
The stark white background of the interface was blinding. Every time he alt-tabbed over to check the transfer queue, it felt like someone was shining a flashlight directly into his retinas. The black text on the white logs swirled, dancing in his exhausted vision.
"I can't do this anymore," Elias muttered, rubbing his temples. He minimized the client's transfer window and opened the browser. He typed the frantic, desperate query into the search bar: FileZilla dark theme update.
He had done this search a dozen times before. For years, the answer had been a frustrating "FileZilla doesn't support native dark mode." He remembered the hacky workarounds—editing configuration files, installing broken XMLs that turned the text black but left the background white, making it unreadable.
But tonight, the search results were different.
At the top of the forum thread he frequented, a new sticky post sat, bold and unread. [Sticky] Version 3.XX Released – UI Update and Theme Support.
Elias sat up straighter, his spine cracking. He clicked the link. “We are pleased to announce native support for dark themes on Windows and Linux...”
His heart did a little flutter—not of romance, but of pure, unadulterated ergonomic relief. He scrambled for his mouse, navigating to the 'Help' menu, then 'Check for Updates.' FileZilla doesn't have a single "Dark Mode" toggle
The progress bar zipped across the screen. Downloading update...
Seconds later, the prompt appeared: Restart FileZilla to complete installation.
Elias took a deep breath. He saved his work on the other monitor. He hovered over the 'OK' button. Click.
The application vanished. For a moment, the desktop wallpaper filled the void. Then, the icon reappeared in the taskbar. Elias clicked it.
The window opened.
It wasn't a harsh flare of white. It was a gentle, matte charcoal. The connection details at the top sat in a deep slate box. The file directory trees were muted grays, the icons subtle and easy on the eyes. Most importantly, the message log at the top—the chaotic stream of status lines—was now white text on a black background.
Elias exhaled a breath he didn't realize he’d been holding. It was beautiful. It matched his IDE. It matched his soul. It matched the night outside.
He didn't have to squint anymore. The burning in his eyes settled into a dull, manageable ache. He clicked 'Connect' to resume the migration. The transfer queue scrolled smoothly, a river of data flowing silently through the dark.
"Finally," he whispered into the darkness, reaching for his cold coffee. "The update that saved my eyesight."
He got back to work, the room illuminated only by the soft, synchronized glow of two dark screens.
FileZilla's dark mode has been a long-requested feature that finally saw major movement in recent development cycles. While it has been natively supported on macOS and Linux for some time by following system-wide appearance settings, Windows users have historically had a much harder time due to the underlying GUI library, wxWidgets. The State of Dark Mode in 2026
The official development roadmap indicated a major shift with FileZilla 3.4.0, scheduled for release in 2026. This version aim to resolve the long-standing "white-out" issue on Windows by updating the project's framework to wxWidgets 3.3, which finally introduces proper dark mode support for Win32 applications.

Here’s a deep review of the FileZilla dark theme situation — specifically focused on the lack of a native dark theme, current workarounds, updates, and whether the situation has improved recently.

The easiest way to get a dark theme is to use the built-in (though still slightly hidden) option introduced in recent updates.
Step-by-step (Updated):
What works: The message log, local/remote directory trees, and transfer queue. What fails: The main toolbar icons (they remain high-contrast/light) and the settings dialog itself. This is why the community continues searching for "UPD" fixes.
On Linux, you can force a dark GTK theme (e.g., Adwaita-dark) for FileZilla via:
GTK_THEME=Adwaita:dark filezilla
But again, not perfect — some text becomes unreadable.
Historically, FileZilla did not support a native dark mode on Windows. Users had to rely on hacky manifests or system-wide overrides. However, with the release of FileZilla Pro 3.67+ and the standard FileZilla Client 3.66+, the developers have slowly introduced partial theming support.
The "UPD" in your search query reflects a community-driven effort to track the latest changes. As of 2025, the situation is:
