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.

Here is the guide to getting a dark theme in FileZilla.

Method 1: The "New" Native Dark Theme (Updated for 2025)

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):

  1. Update to the latest version (Download from official site, version 3.67+).
  2. Open FileZilla.
  3. Go to Edit > Settings (or FileZilla > Preferences on macOS).
  4. Navigate to View > Theme.
  5. Look for the new dropdown: "Color scheme" (This is the UPD you are looking for).
    • Default (Light)
    • Dark (Experimental)
  6. Select Dark.
  7. Restart the application.

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.

Using the Community Patcher (Version 2.0)

A developer released an updated "UPD" patcher in Q4 2024. Here is how to use it safely:

  1. Download the FileZilla Dark Theme Patcher UPD from the official GitHub repo (search for filezilla-dark-theme-reborn).
  2. Ensure FileZilla is closed.
  3. Run the patcher as Administrator.
  4. Click "Patch" – it modifies the internal Qt5 stylesheets.
  5. Launch FileZilla. You should now have a true dark theme, including scrollbars, buttons, and dialogs.

Method 2: The Permanent Resource Hacker Solution (Survives UPD)

Since the official method is fragile, advanced users use a manual patch. This method replaces the internal theming resources. Warning: Do this only if you are comfortable editing executable files.

  1. Download Resource Hacker (freeware).
  2. Navigate to your FileZilla installation folder (e.g., C:\Program Files\FileZilla FTP Client).
  3. Back up filezilla.exe.
  4. Open filezilla.exe in Resource Hacker.
  5. Go to RCData > TDIALOG > 1033.
  6. Search for COLOR_WINDOW and replace references with CLR_DARKGRAY.
  7. Compile and save.

To survive an update (UPD): After every official FileZilla update, re-run Resource Hacker on the new .exe. Keep your modified .exe in a separate folder as a "patch kit."

2. Introduction (Short Paragraph)

FileZilla, one of the most popular FTP clients, has finally introduced an official dark theme. No more eye strain during late-night file transfers. This update brings a modern, fully dark interface that matches your OS preference or can be manually enabled.


1. The Core Problem: No Official Dark Theme in FileZilla

As of FileZilla 3.67.1 (latest stable as of early 2026), there is still no native, built-in dark theme on Windows and Linux.
macOS version inherits the system-wide dark mode (since FileZilla 3.46+), but Windows/Linux users have been waiting for years.

The official stance from the developer (Tim Kosse) has been:

  • Dark mode is low priority.
  • FileZilla uses wxWidgets, which historically had poor dark theme support.
  • The focus remains on stability and core FTP/SFTP features.
