FileView (fv)

A minimal file tree browser for terminal emulators with vim-like keybindings and image preview.

Features

Fast file tree navigation with vim-like keybindings
Git integration - color-coded file status and branch display
Multi-select support for batch operations
Preview panel with support for:
- Text files (with line numbers)
- Images (Kitty/iTerm2/Sixel protocols with auto-detection)
- Directories (file count, size statistics)
- Binary files (hex dump view)
Fuzzy finder (Ctrl+P) for quick file navigation
Copy/cut/paste with internal clipboard
System clipboard integration (path/filename copy)
Pick mode for external tool integration
Callback execution on file selection
Hidden files toggle
Mouse support (click, double-click, scroll, drag-and-drop)
Nerd Fonts icons (enabled by default, disable with --no-icons)

Git Status Colors

When inside a git repository, files are color-coded by their status:

Color	Status
Yellow	Modified
Green	Added / Untracked
Red	Deleted
Cyan	Renamed
Gray	Ignored
Magenta	Conflict

The current branch name is displayed in the status bar.

Image Preview

FileView automatically detects your terminal and selects the optimal image protocol:

Terminal	Protocol	Quality
Kitty	Kitty Graphics	Highest
Ghostty	Kitty Graphics	Highest
Konsole	Kitty Graphics	Highest
iTerm2	iTerm2 Inline	Highest
WezTerm	iTerm2 Inline	Highest
Warp	iTerm2 Inline	Highest
Foot	Sixel	Good
Windows Terminal	Sixel	Good
VS Code	Halfblocks	Basic
Alacritty	Halfblocks	Basic
Other	Auto-detect	Varies

Override with FILEVIEW_IMAGE_PROTOCOL environment variable (see below).

Installation

From crates.io (Recommended)

cargo install fileview

With Chafa support (optional)

For better image quality on terminals without native image protocol support:

# Install libchafa first
# macOS:
brew install chafa

# Ubuntu/Debian:
sudo apt install libchafa-dev

# Then install with chafa feature
cargo install fileview --features chafa

From source

git clone https://github.com/Hiro-Chiba/fileview.git
cd fileview
cargo install --path .

# Or with chafa:
cargo install --path . --features chafa

Requirements

Rust 1.70+
A terminal with true color support (recommended: Ghostty, iTerm2, Alacritty)
