Changes
Refreshed Release Notes experience
We’ve replaced the Release Notes dialog with a dedicated tab that opens automatically after updating Files. This makes it easier to explore what’s new and improved in each release.
Placeholder content for an empty sidebar
When all sidebar sections are hidden, placeholder content is now displayed to improve usability and provide helpful context.

Settings context menu
Right-clicking the settings button now opens a context menu with an option to directly access the settings JSON file.

Customizable size formats
You can now customize how file size units are displayed. This setting is available on the Files & folders settings page, giving you more control over how information is presented.

Automatic encoding detection for ZIP files
We’ve added support for automatic encoding detection when extracting ZIP files. If needed, you can override the encoding manually from the extract archive dialog.

UTF-8 encoding for ZIP creation
When creating ZIP archives, Files now uses UTF-8 encoding by default, ensuring better compatibility across different systems.
