A small script for Windows 10 Home users to compact their WSL2 disks

Inspired by this post on GitHub about WSL2 filling hard disks. Original code by mikemaccana / compact-wsl2-disk.

This script will:

• Check for an elevated shell.
• Find your vhdx file(s) in the default paths of
  • WSL2 distros (C:\Users\<NAME>\AppData\Local\Packages\CanonicalGroupLimited...)
  • Docker WSL2 distros (C:\Users\<NAME>\AppData\Local\Docker)
• Shut down WSL2
• Compact all found disks with diskpart

After that just open another Linux terminal and WSL2 will restart automatically.

Warning

1. I am a stranger on the internet asking you to run a powershell script. You should probably look inside the script compact-wsl2-disk.ps1 and make sure you understand what it does.

2. This will stop WSL. So save your work in Linux.

Usage

Open Powershell as Administrator and run:

powershell.exe .\compact-wsl2-disk.ps1

PRs are welcome!

Please file pull requests instead of just asking for things. Thanks!

Fixes over the original code

The following fixes were made to the original code:

• Script elevation.
• Use Push-Location and Pop-Location to get back to the same location you started at.
• Support for account names with spaces like Kees Bakker.
• Script lines are made yellow.
• PowerShell linted.
