What Sigma File Manager is
Sigma File Manager is a free, open-source file manager for Windows and Linux, with macOS mentioned as supported in principle but without provided builds. It is positioned as a modern replacement for or companion to the default file browser, with a focus on quick navigation, keyboard-friendly workflows, and extension-driven customization.
The README highlights capabilities such as smart global search, tabbed browsing, split view, a built-in extension marketplace, LAN file sharing, quick previews, tags, zip archive handling, and in-app updates. The project also notes support for WSL drives on Windows and alpha-stage network location access for SSHFS, NFS, SMB, and CIFS.
Key features
Tabs and split view
Multiple directories can stay open at once, and any tab can be split into two independent panes for side-by-side navigation and file transfer.
Extensions support
The app includes a built-in marketplace and can also load extensions from local folders, with extensions able to add commands, pages, shortcuts, settings, and more.
LAN sharing and remote locations
Users can share or stream files and folders over a local network with browser access, QR codes, and FTP support, while network locations such as SSHFS, NFS, SMB, and CIFS are listed as alpha-stage support.
File management workflows
The interface includes an address bar, item filters, smart drag and drop, keyboard shortcuts, command palette, dashboard, tags, zip handling, quick view, in-app updates, and WSL drive browsing on Windows.
Customizable interface
The UI can be personalized with custom images, videos, built-in artwork, transparency, blend modes, and other visual controls.
Who it is for
Organizing files across multiple folders
Keep several folders open at once and move between them with tabs and split panes, which is useful when organizing projects or comparing directory contents.
Finding files by imperfect search terms
Search a large drive quickly when you only remember part of a filename, a typo, or an approximate word order.
Power users who prefer keyboard control
Browse files with a keyboard-first workflow using the address bar, shortcuts, and command palette instead of relying only on mouse navigation.
Local sharing and remote access
Share files on a local network with browser access or FTP, or connect to remote locations that the project lists as alpha support.
Users who want a customizable file manager
Extend the manager with custom commands, pages, shortcuts, or settings through the built-in marketplace or local extension folders.
