disktree

A disk usage TUI for your terminal, in the spirit of WizTree and ncdu: scan a drive or folder, see what's taking space at a glance, and delete it safely — without leaving the console.

Fast parallel scan with live progress (1.6M files / 762 GB in ~40 s on a typical NVMe drive)
Size-sorted browser with percentage bars, human-readable sizes, and recursive item counts
Safe deletion: mark any number of files or folders, send them to the Recycle Bin (recoverable) or permanently delete — always behind a confirmation dialog listing exactly what will go
Sizes and percentages update instantly after deletion, no rescan needed
Unreadable (permission-denied) directories are counted and reported, never fatal

Install

cargo install disktree

Usage

disktree                 # scan C:\ (Windows default)
disktree --path D:\Data  # scan a specific directory

Keys

Key	Action
`↑` `↓` / `j` `k`	Move selection
`PgUp` `PgDn` / `Home` `End`	Jump
`Enter` / `→` / `l`	Open directory
`Backspace` / `←` / `h`	Go up
`Space`	Mark / unmark item
`c`	Clear all marks
`d`	Delete marked (or selected) → Recycle Bin, with confirmation
`D`	Delete permanently, with confirmation
`r`	Rescan
`q` / `Esc`	Quit

The footer shows how many items are marked and their total size before you commit to anything.

Notes

Sizes are apparent file sizes (metadata.len()), matching WizTree's default column.
Symlinks and junctions are skipped to avoid cycles and double counting.
Scanning walks directories via read_dir; it does not parse the NTFS MFT, so it works on any filesystem and without admin rights, at the cost of some speed versus MFT-based tools.
Recycle Bin deletion uses the trash crate, so it also works on macOS/Linux (system trash), though Windows is the primary target.
