Show HN: DiskTriage – A simple CLI tool to reclaim space on your Win C drive

A simple CLI tool to reclaim space on your Windows C: drive safely.

It checks SSD health, tracks down bloat (dev tools, AI models, package caches, game stores), and helps you either delete it or move it to another drive — with an interactive terminal menu and built-in safety checks.

Built after a full boot SSD (2.7% free space) caused 1.5-second disk read freezes and triggered a Windows 0x1E_C0000006 (nt!HvpGetCellPaged) blue screen.

git clone https://github.com/ricardoborges/DiskTriage.git
cd DiskTriage

pip install -e .

Run it:

disktriage

Tip: Run PowerShell as Administrator to see physical SSD read/write latency counters via Get-StorageReliabilityCounter.

1. System Health : Checks free space across drives, SSD latency, pagefile location, and recent Windows BSOD bugchecks (last 90 days).
2. Cache Catalog : Scans 50+ known dev and gaming caches (pip ,npm ,cargo ,docker ,huggingface ,pyenv ,gradle ,steam , etc.).
3. Smart Discovery : Finds large unexpected folders in your user profile andAppData .
4. Actionable Fixes :

• Delete : Safely wipe disposable, rebuildable caches.
• Move + Env Var : Move folder to another drive (e.g.D: ) and update user environment variable in registry (HKCU\Environment ).
• Move + NTFS Junction : Move folder and create an NTFS directory junction (mklink /J ), keeping full tracking and 1-click rollback.
• Scan Persistence : Remembers scan results so you don't have to wait for rescans every time you launch.

Tip

Relocate Package Caches & Auto-Update Environment Variables:

You can easily move bulky package caches (such as pip, npm, cargo, or huggingface) from your system drive to a secondary drive (like D:) to free up gigabytes on C:. When using the Move + Env Var option, DiskTriage safely transfers the directory and automatically updates the corresponding Windows user environment variable (HKCU\Environment) with the new path—ensuring your development tools keep working seamlessly without manual configuration.

disktriage                  # Interactive menu (arrow keys + Enter)
disktriage --health         # Health check only (space, latency, BSODs)
disktriage --scan --drive D # Auto-scan and suggest D: as target drive
disktriage --min-gb 1.0     # Only show items larger than 1 GB
disktriage --lang pt-BR     # Force Portuguese (Brasil)
disktriage --lang en-US     # Force English (US)

DiskTriage supports Português (Brasil) (default) and English (US).

• On your first run, DiskTriage will prompt you to choose your preferred language and remember it for subsequent runs.

• You can switch languages at any time from the Main Menu (Option 9 ) or by passing the--lang <codecode> CLI parameter.

• Explicit confirmation : You must type the item name to delete; no accidental single-key deletes.

• Protected paths :WinSxS ,System32 ,Windows\Installer , andProgram Files are strictly blocked.

• Safe file moves : Multi-threadedrobocopy with pre-flight destination free space checks. Source files are only removed after the copy verifies successfully.

• No symlink loops : Never recursively follows junctions or symlinks.
