How to Shrink a WSL2 Virtual Disk

Before you begin

You can check if it’s running with the command wsl.exe --list --verbose in PowerShell:

How to reduce size of docker data volume in Docker Desktop for Windows v2

Docker Desktop for Windows v2, which uses WSL2, stores all image and container files in a separate virtual volume (vhdx). This virtual hard disk file can automatically grow when it needs more space (to a certain limit). Unfortunately, if you reclaim some space, i.e. by removing unused images, vhdx doesn't shrink automatically.

Optimize

wsl --shutdown
Optimize-VHD -Path "$($env:LOCALAPPDATA)\Docker\wsl\data\ext4.vhdx" -Mode Full

GitHub bulk clone

# download a maximum of 1000 @group's repos and organize them under `./group/`:
