A fast, portable dual-pane file manager for Windows, in the spirit of Total Commander.

- Undo / redo for file operations (Ctrl+Z / Ctrl+Y) — copy, move, delete and rename, several levels deep. Deletions are restored from the Recycle Bin, and the undo history is shared with Windows Explorer.
- Folder sizes — press Space on a folder (or size them all at once) and sort by size. With Pro, sizes are remembered, so a folder you have measured stays measured after a restart.
- Instant previews (Ctrl+Q / F3) (Pro) — images, text and code, Markdown, PDF, Office documents, SQLite databases and more, with a full built-in text editor in the F3 window.
- Compare directories (Shift+F2) (Pro) — two folder trees aligned side by side: same, different, or on one side only.
- Find duplicate files by content, and clean them up with undo.
- Archives as folders (Pro) — browse zip, 7z, rar, tar, iso and more like ordinary folders.
- Remote SFTP tabs — work on servers as if they were local folders (Pro).
- Everything search built in, tabs, a folder tree, batch rename, checksums, custom commands (Pro).
- Portable — one exe; settings live next to it in
config.toml, applied the moment you save. An AI agent skill lets you change them by chatting.

look for tags that start with win-.
- Windows 10 / 11, x64. Portable: no installer, nothing written to the registry.
- Markdown, HTML and PDF previews use Microsoft Edge WebView2, which ships with Windows 11.

- Free for personal and home use (non-commercial use) of the basic features — no account needed.
- Commercial use — any use for a company or organisation, or for work, including freelance work — is free to evaluate for 30 days, then requires a paid licence for each user.
- Pro features require a paid licence, including for personal use: the F3 viewer and Ctrl+Q quick view, browsing archives as folders, remembered folder sizes, folder compare, custom commands and remote SFTP. Try them free for 30 days from inside the app — no card, no account.
- One licence covers 2 computers (say, work and home) and includes future updates. Licence holders get email support.
- Activating or starting a trial contacts our licence server once; after that the licence is checked offline. (The update check at start-up is separate, sends no personal data and can be turned off.)

skills/obcmd-config teaches an AI agent how to edit OB Commander's config.toml — colors, themes, fonts, columns,
shortcuts, toolbar, menus and more. It follows the open Agent Skills format, so the same folder
works in any agent that supports it.
