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

Developer Ricardo Borges released DiskTriage, a GPL-3.0 command-line tool that reclaims space on Windows C: drives by scanning 50+ dev and gaming caches including pip, npm, cargo, docker, huggingface, pyenv, gradle, and steam. DiskTriage was built after a boot SSD at 2.7% free space caused 1.5-second disk read freezes and a Windows 0x1E_C0000006 (nt!HvpGetCellPaged) blue screen, and it offers delete, move-plus-environment-variable, and move-plus-NTFS-junction fixes with safety checks that block WinSxS, System32, Windows\Installer, and Program Files.

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 Install dependencies and the disktriage CLI 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 and AppData . 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 , and Program Files are strictly blocked. - Safe file moves : Multi-threaded robocopy with pre-flight destination free space checks.
