Release Notes

Summary: Navigator performance improvements, generated thumbnails, extension themes, printing, file previews, new shortcuts, address editor improvements, status center redesign, and tab/navigation polish.

Printing

Print selected files directly from the navigator using the context menu, actions menu, or Ctrl+O.

• Supported formats: images, PDF, text formats;
• Quick exit: close the print view with Escape;

File Drop To Tabs

Drag files or directories onto tabs to move or copy them into another tab's directory.

• Drop target tabs: tabs become drop targets while dragging files in the navigator;
• Hover activation: hovering over a tab while dragging can switch to that tab before dropping;
• Split tabs: directory tab groups keep their normal drop behavior while preserving split-view tab structure;

File Preview In Info Panel

The info panel can now preview all Quick View-supported file types, not just images and videos.

• Media previews: images use generated thumbnails, videos and audio include native controls, and PDFs render inline;
• Text previews: text files show a compact decoded preview with a safe size limit;
• Fallbacks: unsupported files and folders keep simple icon placeholders;

Navigator List Columns

List view has more optional columns and better inline metadata control.

• Created column: show and sort by creation date;
• Tags column: show tags directly in list view and add, remove, or edit tags from the column;

Extensions

App Themes From Extensions

Extensions can now contribute full app color themes. Installed theme extensions appear in the theme selector.

Icon Themes From Extensions

Extensions can now contribute navigator icon themes for folders and files.

• Separate choices: choose folder and file icon themes independently in Settings > UI appearance > Icon Theme;
• Built-in and extension themes: use the built-in default/system icon themes or any enabled extension-provided theme;
• Theme matching: contributed themes can define icons by file extension, file name, folder name, and expanded folder state;

New Settings

• Bold active tab text: make the active tab title bold (Settings > Tabs > Tab appearance > Bold active tab text);

New Shortcuts

• Toggle split view (Ctrl+S): show or hide split view in the navigator;
• Restore closed tab (Ctrl+Shift+T): restore the most recently closed tab group;
• Create file / directory (Ctrl+Shift+M / Ctrl+Shift+N): create a new file or directory in the current directory;

• Navigate to parent directory (Alt+Up): go to the parent directory;
• Mouse history buttons (Mouse Button 4 / Mouse Button 5): navigate back and forward with mouse side buttons;

UX Improvements

Large Directory Performance

Navigation, quick search, and media-heavy folders are more responsive and use less memory.

• Generated thumbnails: image and video thumbnails are generated at smaller sizes instead of loading full media into every file card;
• Progressive images: grid image cards can show a blurred low-resolution thumbnail before the final thumbnail is ready;
• Thumbnail cancellation: thumbnail generation can be cancelled when the folder or visible entri

Release Notes

Summary: Extensions system with marketplace, LAN file sharing, quick access menu, zip archives, WSL drives, tag editing, enhanced quick view and search, visual effects improvements, and many UX and stability improvements.

New Features

Extensions System

Full extension system with open marketplace.

• Marketplace: browse, install, and manage extensions from the marketplace;
• Local installation: you can install extensions from local folder;
• Command palette: new way to activate app and extension commands;
• Capabilities: extensions can register local and global shortcuts, context menu items, settings, whole pages, and commands;
• Versioning: you can install different versions of extensions and enable auto update;
• Localization: extensions can provide translations for different langauges;
• Binary management: extensions can use binaries (ffmpeg, deno, node, yt-dlp, 7z, and any other existing binary);
• Sandboxed execution: extensions run in isolated ESM sandboxes with granular permissions;

Default file manager

You can now make SFM the default file manager on Windows (Settings > Experimental). When this setting is enabled, most system file actions will be routed to SFM:

• File Explorer app icon;
• Ctrl+E shortcut;
• Reveal file in folder;
• Show downloads (when you download a file in browser);
• Terminal commands: "start {path}", "code {path}", etc.
• And more;

Native system views like "Recycle Bin", "Control panel", and such deeply integrated programs are delegated back to native File Explorer.

LAN Sharing

Share and stream files and directories over your local network directly from the app.

Access LAN sharing from the toolbar button in the navigator or from the context menu on any file or directory. When a share is active, a QR code and shareable URLs are displayed. Two modes are available:

• Stream: stream files and directories to any device on your network via a web browser;
• FTP: share files over FTP for direct access from other apps. You can both download and upload files from and to the computer from other device;

Quick Access Menu

The "Dashboard" button in the sidebar now acts as a quick access menu. Hovering over it opens a panel showing your Favorites and Tagged items.

All items in the panel are real directory entries - you can drag and drop items in and out, open context menus with right click, and perform any standard file operations.

Can be disabled in Settings > UI appearance > Open quick access panel on hover.

Zip Archives

Compress and extract zip archives directly from the file browser actions menu:

• Extract: extract a .zip file to the current directory or to a named folder;
• Compress: compress selected files and directories into a .zip archive;

WSL Drives Detection

On Windows, the app now automatically detects installed WSL distributions and displays their drives in the navigator, allowing you to browse WSL file systems natively.

Tag Editing

You can now edit tag names and colors. Open the tag selector on any file or directory to rename tags, change their color, or delete them.

In-App Updates

You can now download and install updates directly from the update notification without leaving the app.

Copy Path

Added "Copy path" option to the file and directory context menu.

Close Duplicate Tabs

Added the ability to close duplicate tabs from the tab bar, removing all tabs that point to the same directory.

Home & Dashboard Context Menus

Items on the home page and dashboard now have full context menus, matching the functionalit
