Files 4.0.39 Delivers Customizable Toolbar Innovation
The Files app released version 4.0.39 on April 23, 2026, introducing a comprehensive customizable toolbar system that allows Windows 11 users to tailor their file management experience. This third-party file manager now offers personalization options that Microsoft's native File Explorer lacks, creating a stark contrast between modern interface design and Windows 11's aging file management approach.
The customizable toolbar represents a significant evolution in Files' user interface philosophy. Users can now drag and drop commands, rearrange toolbar elements, and create personalized workflows that match their specific file management needs. The implementation includes support for custom keyboard shortcuts, contextual menu integration, and adaptive toolbar layouts that respond to different file types and folder contexts.
This update builds on Files' reputation as a modern alternative to Windows 11's File Explorer, which has remained largely unchanged since Windows 10. The toolbar customization feature demonstrates how third-party developers are addressing user interface limitations that Microsoft hasn't prioritized in recent Windows 11 updates. The timing of this release coincides with growing user frustration over File Explorer's static interface and limited personalization options.
Files has consistently pushed boundaries in Windows file management, previously introducing features like tabbed browsing, modern context menus, and improved search functionality. The 4.0.39 release continues this trend by addressing one of the most requested features from the Files community: the ability to customize the toolbar layout according to individual workflow preferences.
Windows 11 Users Gain Advanced File Management Options
The Files 4.0.39 update primarily benefits Windows 11 users who rely heavily on file management for professional workflows, content creation, and system administration tasks. Power users, developers, and IT professionals who frequently navigate complex directory structures will find the customizable toolbar particularly valuable for streamlining repetitive tasks and creating efficient file management workflows.
The update affects all existing Files app users across Windows 11 versions 21H2, 22H2, and 23H2, with automatic update delivery through the Microsoft Store. Users running Windows 10 can also access the new toolbar features, though the visual integration works best with Windows 11's design language. The customizable toolbar functionality requires no additional system resources beyond the standard Files app installation, making it accessible to users across different hardware configurations.
Organizations using Files as their standard file manager will benefit from the toolbar customization options, which can be configured to match specific departmental workflows or compliance requirements. The feature particularly impacts users who previously relied on multiple file management tools or complex keyboard shortcuts to achieve efficient file operations.
How to Configure Files 4.0.39 Customizable Toolbar
Users can access the new toolbar customization features through the Files app settings menu, located under the 'Appearance' section. The configuration interface allows drag-and-drop toolbar arrangement, with real-time preview of changes before applying them permanently. Users can add frequently used commands like copy, paste, delete, properties, and custom scripts to their personalized toolbar layout.
The customization process includes preset toolbar configurations for different user types: basic users, power users, developers, and system administrators. Each preset optimizes toolbar layout for specific workflows while maintaining the option for complete manual customization. Advanced users can create multiple toolbar profiles that automatically switch based on folder location, file types, or time-based rules.
To enable the customizable toolbar, users should update Files through the Microsoft Store, navigate to Settings > Appearance > Toolbar, and select 'Enable Custom Toolbar.' The interface supports keyboard shortcuts for toolbar commands, with customizable hotkey assignment through the Settings > Keyboard section. Users can export and import toolbar configurations, enabling consistent setups across multiple devices or team environments.
