TreeMap — 21 World-Class Cross-Platform Features
TreeMap is a high-performance, local-first disk-space analyzer and storage workbench built for Windows, macOS, and Linux. Built with zero frontend dependencies and a lightweight Node.js/Electron architecture, TreeMap combines near-instant scanning with safe, intelligent storage management across all your devices.
Key Features & Capabilities
Group A: Speed & Accuracy Core
Instant Scan Engine (A1): Reads raw filesystem structures—like the NTFS MFT, APFS getattrlistbulk, and Linux batched statx—to deliver near-instant initial scans and keep your disk index updated in real time.
Byte-Accurate CoW Sizing (A2): Correctly calculates shared versus exclusive disk usage across APFS clones, Btrfs reflinks, and NTFS hard links so your folder totals reflect actual free-space impact.
Placeholder & Cloud-Aware Sizing (A3): Accurately separates local disk usage from total cloud footprint for evicted iCloud items, OneDrive Files On-Demand, and sparse files.
Instant Size-Aware Search (A4): Delivers sub-100ms, type-ahead global search across multi-million file indexes with flexible size, age, and file-type filters.
Topology & Physical Mapping (A5): Maps logical volumes, APFS containers, LVM pools, and Storage Spaces back to their physical drives so you know exactly which physical disk is filling up.
Group B: Safety & Automation
Autopilot Policy Engine (B1): Automates background disk maintenance using customizable, capped cleanup rules with mandatory dry-run approvals to prevent unexpected deletions.
Open-File Guard (B2): Inspects system handles before every deletion to warn you if a file is actively locked or open in another application.
Time Capsule Safety Net (B3): Secures automated cleanups by staging items in a size-capped local buffer before trashing, enabling instant 30-day restores.
Snapshot Restore Engine (B4): Scans VSS, APFS, and Btrfs snapshots to let you recover deleted files directly from local system restore points.
Zombie-Handle Detector (B5): Identifies and reclaims hidden disk space consumed by deleted files that are still held open by orphaned background processes.
Group C: Intelligence & Detection
Cost Intelligence (C1): Projects your real-world cloud storage costs across major providers and calculates instant monthly savings for reclaiming space.
Media Compression Advisor (C2): Recommends non-destructive, hardware-accelerated video re-encoding candidates with verified frame checks before trashing oversized originals.
Download Provenance Tracker (C3): Uncovers where and when old installer archives and large downloads originated by inspecting hidden OS download metadata.
SMART Drive Health Correlation (C4): Combines raw drive-wear metrics with disk-growth trends to project when you will run out of physical space or need a drive replacement.
Security & Secrets Scanner (C5): Flags exposed private keys, .env files, and API credentials lying in unsafe user locations like Downloads or Desktop.
Package Ecosystem Cleaner (C6): Detects orphaned node_modules, venv, Homebrew, and Cargo build caches whose parent projects have been removed.
Game Library Awareness (C7): Categorizes Steam, Epic, GOG, and itch.io installs into base files, DLC, and shader caches with safe one-click cache clearing.
Unified Known-Offenders Catalog (C8): Powers automated cleanup suggestions using versioned, community-driven rule packs for system build caches, temporary files, and log growth.
Group D: Reach & Ecosystem
LAN Fleet View (D1): Discovers and displays disk usage summaries across all opted-in TreeMap instances on your local network using zero-cloud mDNS pairing.
Native Shell Integration (D2): Adds a "Scan with TreeMap" context-menu entry directly into Windows Explorer, macOS Finder, and Linux file managers.
Portable Triage Mode (D3): Runs fully self-contained from external USB drives to troubleshoot target machines without leaving residual files or registry keys on the host system.
