WSL Disk Cleanup & Reclaiming Space

1. Run wsl_disk_cleanup.sh

• Purpose: Frees up disk space by cleaning up unnecessary files and package caches inside your WSL instance.
• How to Use:
  1. Place wsl_disk_cleanup.sh in your Linux home directory (or any preferred location).
  2. Make it executable:

     chmod +x wsl_disk_cleanup.sh

  3. Run the script:

     ./wsl_disk_cleanup.sh

• What to Expect:
  The script will:
  • Clean up package cache with sudo apt-get clean
  • Remove unused packages with sudo apt-get autoremove
  • Clean temporary files and logs
  • You will see output messages summarizing freed space and actions taken.

2. Reclaim Space Using Optimize-VHD

• Purpose: Shrinks the virtual disk file used by WSL2 to reclaim freed space back on your Windows host.
• How to Use:
  1. Open PowerShell as Administrator.
  2. Run:

     Optimize-VHD -Path "C:\Users\<username>\AppData\Local\Packages\CanonicalGroupLimited.Ubuntu22.04LTS_79rhkp1fndgsc\LocalState\ext4.vhdx" -Mode Full

• What to Expect:
  This operation may take several minutes. When finished, the ext4.vhdx file will be smaller if there was unused space to reclaim.

3. Finding Your VHDX Path

• Each WSL distribution has its own vhdx file.
• The path generally looks like:

  C:\Users\<YourUsername>\AppData\Local\Packages\<DistroPackageName>\LocalState\ext4.vhdx
  

• How to Find It:
  1. List installed WSL distributions:

     wsl --list --verbose

  2. Find the folder in:

     %USERPROFILE%\AppData\Local\Packages
     

     Matching your distribution (e.g., contains Ubuntu22.04LTS).
  3. The vhdx file is inside that folder’s LocalState directory.
