FileManagerTUI vs nnn

FileManagerTUI is a free terminal file manager built with Rust and Ratatui, available for Linux, macOS, and Windows. Its dual-pane interface combines a file tree with a live preview and syntax highlighting. Users can navigate with Vim-style keys or arrow keys, search project files with a Ctrl+P fuzzy finder, and filter directories inline. File operations include creating, renaming, deleting, copying, cutting, pasting, and undoing. The inline editor supports syntax highlighting, undo and redo, find and replace, auto-indent, text selection, and mouse cursor positioning. An integrated PTY shell panel uses VT100 emulation, and notebook previews render Jupyter cells with syntax highlighting. Files over a configurable threshold use a head/tail preview mode. The software can browse S3 buckets through the AWS CLI, but that mode is read-only and requires valid AWS credentials. Building from source requires a Rust toolchain. It is distributed under the MIT License, which permits use, modification, distribution, sublicensing, and resale; the software is provided without warranty or liability.

nnn is a terminal file manager designed to be small, fast and nearly zero-configuration. It handles copying, moving, deleting, archiving and linking selections, alongside batch renaming, disk-usage analysis, app launching and file picking. Navigation includes contexts, sessions, bookmarks and directory marks, while search options include instant filtering, fuzzy matching, regular expressions and string filters. It provides directory and text previews, and can create, list, extract and mount archives. Plugins can add functions such as live previews, disk mounting, file comparison and uploads. Remote mounts require optional sshfs or rclone dependencies. The project says nnn typically needs less than 3.5 MB of resident memory; it has no configuration file and uses defaults, with optional environment-variable settings. It is free and open source under the BSD-2-Clause license, and is listed for Android, Linux, macOS and Windows. The project offers packages and a statically linked binary, or users can compile it from source.
