Features
What is in the box
CrapCleaner covers cleanup, disk analysis and day to day system management. Everything below is in the current release. Features a platform cannot provide are hidden on that platform rather than shown broken.
Cleanup
- More than 75 cleanup targets, grouped by where they come from rather than by an arbitrary score.
- Windows system: user and system TEMP, CBS servicing logs, Delivery Optimization cache, font cache, certificate cache, DirectX and GPU shader caches, Prefetch traces.
- Developer tools: VS Code, Cursor, Windsurf, Zed, the JetBrains IDEs, Android SDK build caches, Gradle daemon logs, Bun, Unity, Godot, Unreal DDC and CMake build output.
- Package managers: npm, yarn, pnpm, pip, uv, poetry, conda, NuGet, Cargo, Go build cache, Maven, WinGet, Chocolatey and Scoop.
- Games and launchers: Steam shader and depot caches, Epic Games, EA Desktop, Ubisoft Connect, Battle.net, GOG Galaxy, Riot crash logs and FiveM.
- Browsers: Chrome, Edge, Brave, Opera, Vivaldi, Arc, Firefox, LibreWolf, Waterfox and Floorp HTTP and GPU caches. Bookmarks, passwords, history and active sessions are left alone.
- Linux package managers: APT, DNF, pacman, Flatpak and Snap caches.
- Pre-cleanup preview: a manifest of every candidate item with its size, safety level, whether it is reversible and whether it needs administrator rights.
Dashboard and live vitals
- Reclaimable space across every mounted drive, with a breakdown of the largest categories coloured by safety level.
- Live system readings for memory, processor, graphics and network, each with a rolling 60 sample history strip.
- Graphics reporting covering temperature and VRAM usage where the driver exposes it, through NVML on NVIDIA and the DRM interface on Linux.
- Drive cards showing used, free and total capacity for every partition the system reports.
Storage analysis
- Proportional storage map where each cell's area maps to its size, so the largest consumers are visible at a glance. Drill into folders, navigate with the keyboard, and hover for the full path.
- Breakdown by file type across videos, images, audio, code, archives, documents, executables, databases and disk images.
- Drive health reporting media type, bus type, filesystem, capacity and TRIM support.
- Quick access bookmarks for home, downloads, documents, application data, temp and video folders, plus your own saved favourites.
- Cancellable, with live progress, so a scan of a large tree is never a commitment.
Deep scan tools
- Duplicate finder using a three stage pipeline: exact size match, then an 8 KB header hash, then full SHA-256 verification. Resolution helpers keep the oldest, newest, shortest path or first result.
- Large file finder for the files actually responsible for a full disk.
- AI data inspector that reports GGUF weights, safetensors and checkpoints for Ollama, LM Studio and Hugging Face strictly read-only. It is never a cleanup target.
- Old installer detector for leftover
.msi,.exe,.iso,.deb,.rpm,.dmgand.pkgfiles. - Crash dump analyser for user-mode dumps, kernel minidumps, memory dumps and core dumps, with the owning application named where it can be determined.
- Virtual machine and container storage: WSL2 virtual disks, Docker storage, and VirtualBox, VMware and Hyper-V disk images.
System management
- Startup applications: everything configured to run at login, with its location, state, inferred publisher, resolved executable, whether that executable still exists, and an estimated boot impact. Enable, disable, add or remove entries.
- Services: Windows services or systemd units with status, startup type, description and account. Start, stop, restart and change startup type. Critical components are protected from being stopped or disabled.
- System updates: pending Windows updates with KB identifiers, severity and size, or distribution updates from apt, dnf, pacman or zypper with security errata marked and reboot detection.
- Application updates: every available upgrade from the package managers installed on the machine, in one list. Upgrade one package, a selection, or everything a manager offers.
- Recycle Bin and Trash inspector reporting recoverable space, item count and the oldest and newest entries.
Memory
- Full memory report: total, in use, available, cached and standby, committed against the commit limit, plus swap or pagefile usage. Counters the platform does not expose are shown as unknown, never as zero.
- Explained reclamation actions. Only the actions the running kernel can perform are listed, and each names the exact call it will make.
- No process is ever terminated, no priority is changed, and no other application's memory is touched.
- An honest limitation: no public driver API lets a normal application flush another application's VRAM, so CrapCleaner ships a VRAM diagnostic and does not pretend to offer a flush.
- No performance claims. Windows and Linux already manage memory automatically. This is optional maintenance, not an optimisation.
Reports, history and configuration
- Export storage breakdowns, scan results, disk health and audit history to JSON, CSV or plain text.
- Local audit history of every cleanup, with lifetime totals.
- Preferences with dedicated sub-navigation tabs for Theme Gallery, Custom Theme Studio, Safety & Protection, Exclusions & Roots, Scan Performance, Category Rules, and Backup & Sync. Settings are stored locally and can be exported, imported or reset.
- Your own exclusions on top of the built-in protected paths, so anything you want kept stays kept.
Interface and Theming
- Custom Theme Studio: design, fine-tune and live-preview personal themes using a perceptual color theory engine with WCAG 2.1 AAA contrast enforcement, 6 harmony mood styles (Cohesive, Vibrant, Muted, OLED Pure, Pastel, Minimal), 15 curated designer presets, magic dice generator and theme JSON export/import.
- 43 built-in themes across modern dark, light and pastel, retro and vintage, cyber and synth, code editor palettes, and warm and nature categories.
- A true black OLED theme that lets OLED panels switch pixels off while keeping text and borders readable.
- Keyboard shortcuts for the first ten views, scanning, refreshing, searching and cancelling. F1 opens the safety and technical documentation.
- A reduce motion preference that disables the theme cross-fade and other transitions.
- Built-in help covering the design principles, the reasoning behind omitting a registry cleaner, the protected paths architecture, and a one click system diagnostics copy for bug reports.

A scan is read-only. Nothing is deleted until you select categories and confirm.
