DiskPilot

Problem

Windows’ built-in disk cleanup is slow, superficial, and never shows why a file should be deleted. Third-party tools are either filled with ads, cost money, or delete files without explanation — making users nervous about losing something important.

Solution

DiskPilot scans all drives and categorizes files into four confidence tiers, so you never delete something you’ll regret:

• SAFE — Guaranteed safe to delete (temp files, cache, logs)
• RECOMMENDED — Very likely redundant (old installers, duplicates, torrents)
• SUGGESTED — Probably fine, but worth checking (old archives, backups)
• ASK — Only you know if you need them (old media files, abandoned projects)

Key Features

• Smart scanning — Catalogs all files in a SQLite database with automatic skipping of developer directories (node_modules, .venv, __pycache__, etc.)
• Duplicate finder — Finds identical files across drives and suggests keeping the newest
• Version detection — Finds older versions of the same installer and flags them
• Piracy detection — Flags known cracks, keygens, and activators as security risks
• Drive organization — Assign purposes to drives (Games, Projects, Media) and find misplaced files
• 3-layer system protection — System files are protected during scanning, analysis, and deletion
• Recycle bin by default — Nothing is permanently deleted unless you actively choose it

Technical Architecture

The application is built with a clear separation of concerns:

• UI layer — CustomTkinter + ttk.Treeview with dark theme
• Scanner — Filesystem walker with intelligent filtering and categorization
• Smart Analyzer — 4-tier confidence engine with duplicate/version/piracy detection
• Database — SQLite with WAL mode and batch inserts for performance
• Organizer — Deletion queue with recycle bin support

Result

A free, open-source tool that gives Windows users full control over disk cleanup with transparent explanations for every file. MIT license, available on GitHub.
