This repository provides utility scripts to compact the WSL (Windows Subsystem for Linux) VHD/VHDX file, which can grow over time. Two versions are available:

• PowerShell Script
• Batch Script

Key Features:

• Automatic Detection: Automatically locates the WSL VHD/VHDX file (e.g., ext4.vhdx) in common installation paths.
• Safe Operation: Checks if the VHD is already attached and detaches it if necessary.
• Read-Only Attachment: Attaches the VHD in read-only mode to ensure data integrity.
• Automated Diskpart Integration: Generates and executes a temporary Diskpart script to perform attach, compact, and detach operations.
• Ease of Use: Minimal configuration required—simply stop WSL and run the script with administrative privileges.

Prerequisites:

• WSL Shutdown: Run wsl --shutdown before executing the scripts.
• Administrator Privileges: The scripts must be run as an administrator.
• Supported OS: Windows systems running WSL.

Usage:

• PowerShell Script:
  Open PowerShell as an administrator, navigate to the repository directory, and execute:

  .\CompactWSLVHD.ps1
