"Sigma File Manager" is a free, open-source, quickly evolving, modern file manager (explorer / browser) app for Windows and Linux (Mac is supported but the build is not provided yet, can be built from source). - aleksey-hoffman/sigma-file-manager
I'm building modern open-source file manager that aims to be the best at everything. Created with real skills, before the vibecoding slop.
Here's some of its major features:
- Smart global search: Finds files and folders in seconds (searches full `1TB` drive in under 2 seconds on average). Its typo correction system handles typos, wrong case, wrong word order, missing words, missing symbols, and missing file extension. - Tabs: Keep multiple directories open and switch between them instantly. - Split view: Any tab can be split into 2 panes which you can navigate independently and transfer files between them easily. - Extensions and marketplace: Install extensions from the built-in marketplace or local folders. Extensions can add commands, pages, shortcuts, settings, and more. - Default file manager: On Windows, Sigma can replace File Explorer for most everyday file actions. - LAN file sharing: Share or stream files and folders over your local network, with browser access, QR codes, and FTP support. - Network locations (Alpha stage): Connect to remote locations such as SSHFS, NFS, SMB, and CIFS. - Address bar: Navigate with the keyboard, autocomplete paths, and quickly jump to parent folders. - Item filter: Narrow large folders with glob patterns and property filters for size, dates, MIME type, and more. - Smart drag and drop: Move or copy local files more comfortably, and handle web drops more smoothly. - Shortcuts and command palette: Most actions are keyboard-friendly, with global shortcuts and a fast command palette for app and extension commands. - Home banner and visual effects: Personalize the UI with custom images, videos, built-in artwork, transparency, blend modes, and other style controls. - Dashboard and quick access: Reach favorites, tagged files, most visited locations, and history data from one central area. - Tags: Organize your files and folders with tags. - Zip archives: Compress files into `.zip` archives and extract them without leaving the app. - In-app updates: Download and install updates directly from update notifications. - Quick view: Instantly preview images, videos, audio, PDFs, and text files with `Space`, then move through files without opening external apps. - WSL drives: On Windows, browse detected WSL distributions directly in the navigator. - Localization: The app has translations for all most used languages. - And more. Extensions provide additional features like video downloading (1000+ sites supported, including YouTube, Twitch, etc.), media converter, image size optimizer, etc.
Huge congratulations, Aleksey! I’ve been following the development of your SFM pretty much from the start and I’m thrilled to see how far you’ve come! It’s a pleasure to work with SFM and I hope you’ll keep delighting us with updates for a long time to come! The Extensions Marketplace, in particular, could do with a few more ideas!
As someone who moved from Windows to macOS about 15 years ago, I still occasionally miss Total Commander 😄
I’ve never fully gotten used to Finder. For me, file management is one of those core workflows where small UX improvements save a surprising amount of time.
A few features immediately caught my eye:
ZIP archives without leaving the app
Split view
Fast search
Keyboard-first navigation
One question: how far have you gone with hotkeys and folder navigation?
For example, can I assign shortcuts to jump directly to specific folders, favorites, projects, or frequently used locations? Fast navigation is probably one of the biggest productivity multipliers in a file manager.
Congrats on the launch and good luck today 🚀
Great idea, I hope there will be a macOS version as well. I know many users who have to work on at least two operating systems and then it would be nice to have the same UI no matter where you currently juggle your files.
File managers are one of those categories where the defaults (Finder, Windows Explorer) are good enough that most people don't switch unless something specific annoys them. Curious what the core workflow improvements are here, whether it's around things like batch renaming, directory diffing, or something more opinionated about how tabs and panes work. Also wondering how the cross-platform support holds up in practice, specifically whether the Linux build gets the same attention as the Mac and Windows ones or tends to lag on fixes.
Congrats for the launch!
